(updated 23 October 2026)

For years, video game metadata was the back-of-the-box stuff: a title, a publisher, a release date, a genre. Someone entered it when the game launched and nobody looked at it again.

That is not how games are sold or played anymore. A single game can now sit on five platforms, three cloud services and a subscription catalog at the same time, carry a different age rating in every region, and change its modes with every new season. Platforms that bring games together from several providers, such as cloud, streaming and subscription services, smart TV and OEM gaming hubs, and ACR platforms receive every one of those versions. Their job is to turn them into one accurate entry a player can trust.

Video game metadata is the structured information that makes that possible: what a game is, who made it, how it plays, where it's available and who it's rated for. This guide covers what it includes, why it keeps changing after launch, the problem of matching the same game across providers, and what it does for each type of platform.

What is video game metadata?

Metadata describes an item, i.e. it is any information that summarizes basic details about the item, which can make finding and working with particular data easier. For example, the ingredients listed behind a box of cookies is metadata describing the contents of the cookie.

Similarly, video game metadata refers to descriptors about the game that not only give you an overview of the game like the developer's name, publisher's name, release date, game description, and so on, but it also helps the people using this video game data easily understand what the game has to offer without having to purchase or play the game themselves.

What constitutes video game metadata

Video game metadata could be any information that gives the reader insights about the game. From the release date to the game franchise it belongs to, any information that tells us something about the game can be considered game metadata. Let's take the example of Marvel Rivals, a free-to-play team-based hero shooter released in December 2024. The metadata for this game would look something like this.

In practice, game metadata falls into seven groups:

• core identifiers: title, developer, publisher, platform, release date, editions and DLC

• descriptive information: genres, themes, game mechanics, game modes, each weighted by how strongly it features in the game

• technical details: system requirements, supported languages, controller support, cross-play

• regional details: age ratings, localized titles

• availability: which platforms, stores, cloud services and subscription catalogs carry the game, and in which regions

• editorial and media: descriptions, key features, artwork, screenshots and trailers

• relationships: franchises, series, sequels and remasters

Video game metadata changes after launch

For most of gaming's history, a game's metadata could be written at release and left alone. Live-service games changed that. Marvel Rivals has logged 56 live-service entries in Gameopedia's records since launch, 10 of them being seasons.

Each one can change what the record should say.

• A new season can add characters, maps or modes.

• An update can add cross-play.

• A paid game can go free-to-play.

• A game can join a subscription catalog, then leave it.

A record that was right at launch can be wrong by the third season, so freshness is now part of what makes metadata good.

The multi-provider catalog problem with video game metadata

Any platform that takes games from more than one provider inherits every provider's way of describing them. Each source has its own identifiers, its own spelling of the title, its own edition names and its own availability labels. Put side by side, they disagree.

The overlap is bigger than most teams expect. Popular games tend to sit in several catalogs at once, so a platform that pulls feeds from multiple providers receives the same game several times over, each time described a little differently. Before it has shown a player anything, it already has duplicates to resolve.

To show each of those games once, and correctly, the platform has to work out:

• which records across stores, services and regions are the same game

• one consistent title and set of artwork

• which services the game is actually on

• whether it can be streamed from the cloud

• which controllers it supports

• which edition the player gets, and which DLC belongs to it

• the right age rating for each region

Title matching handles the easy cases. It breaks on a Deluxe Edition listed as a separate game, a remaster merged with the original, or a regional title that does not match the English one. This is where video game metadata adds the most value: one identity per game that every provider's record maps to.

This leads to our next question:

Who needs metadata for video games?

Everybody that is a part of the gaming ecosystem, from the retailer to the consumer, uses video game metadata at some level. The format in which the data is presented and how it is used can vary depending on the requirement. The need is greatest for platforms that bring games together from several providers.

Video game metadata for cloud, streaming and subscription platforms

A cloud or subscription service builds its catalog from many providers, and each one describes the same game its own way. One source says "Play via cloud," another says "Included with subscription," a third says "Stream instantly," and all three can be true of one title. Without shared video game metadata, the player sees three records and no clear answer to where and how to play. Metadata for cloud gaming platforms starts with one identity per game and one consistent set of availability labels, so the service can show a single entry with every way to access it.

Cloud also adds questions a console store never had to answer: whether a game can be played without a controller, which regions it can be streamed in, and whether it is about to leave the subscription.

Video game metadata for smart TV and OEM gaming hubs

A gaming hub on a smart TV or other device pulls games from several partners into one screen. The same game then arrives with a different title in each region, a different age rating from the local ratings body (ESRB, PEGI, USK and CERO, among others), and different languages and release dates. Marvel Rivals, for example, is rated Teen by the ESRB in the US, 12 by PEGI in Europe and 12 by the USK in Germany. If the hub cannot tie those regional records to the right game and edition, the home screen can show duplicates and the wrong rating for the market. Localized game metadata keeps one game recognizable in every country it is sold in.

The same metadata powers the hub's recommendations and personalization, so the home screen can suggest games based on what a household actually plays.

Video game metadata for automatic content recognition (ACR)

Automatic Content Recognition (ACR) is identification technology that uses a large reference database to recognize content (video, audio, or digital images) played on a media device. For games, that content can reach the screen from a console, from a cloud stream or from a game running natively on the TV.

Recognizing that a game is being played is only the first step. ACR platforms also need to know which game it is and what kind of game it is. That takes a capture library of real gameplay to match against, title identification that resolves each match to the right game, and rich metadata on top. This is how Gameopedia works with ACR partners today.

Once gameplay on the device can be identified and described, it supports audience measurement, ad targeting, recommendations and gaming hub personalization. Because live-service games keep changing how they look, the capture library has to keep up with them too.

Video game metadata for e-retailers and app stores

A retailer's goal is to engage their customer and attend to their needs or solve a problem they have.

Your first thought might have been retailers want to sell more but it might be more prudent in the long run to gain the trust and loyalty of their existing user base. And gamers are a loyal bunch.

The best way to gain a gamer's trust? Understand what you are selling inside out.

With detailed and descriptive metadata and good metadata management policies, the store can display the right games to the customer most likely to buy them. What are these "right games"? They are games which have the features that a customer wants, or a game by the same developer whose earlier work the customer enjoyed for example. This is information that the customer needs to make a decision. By offering the right games, the store improves the customer's experience and earns their trust. Online, metadata replaced the store shelf.

Let's consider the example of Monster Hunter Wilds. It was one of the most anticipated releases of 2025, but not everybody was looking forward to it. This segment of your user base would prefer not to be inundated with content and promotional material regarding the game. For these users, "Monster Hunter Wilds" is the definition of not being the "right game".

Combining comprehensive game metadata with user behavior, your game store can display content that actually appeals to the audience, making their experience more personalized.

Video game metadata for advertisers

People use the same item for different purposes. While a gamer could be looking for a mouse suitable for gaming, an office employee will look for a mouse more suited for day-to-day use, and the features each looks for change accordingly. This means that to advertise the right product to the right consumer, it is vital to understand the "why" and not just the "what". The "Mario Kart" franchise is one of Nintendo's best-selling series, and its latest entry, Mario Kart World, is enjoyed across all age groups by gamers who have different expectations from their gaming habit.

Some gamers play because they like to win competitive games. Some play games purely as a social activity that they indulge in with family or friends. There's another group of gamers who have a hard day at work, and would like to unwind in the evening, without having to worry about complex plotlines or learn advanced gameplay mechanics.

The beauty of "Mario Kart World" is that it has something for all the types of gamers described above, but an advertiser can't expect to use one campaign to reach out to all three groups. Each of them needs a different pitch. What keywords do they look out for when making a game purchase? What features do they expect from a game? Do they expect their games to look simple, or photorealistic with complex mechanics?

With comprehensive game metadata, ad networks get more context for their targeting, making it more personalized while showing why the said product is best suited for your needs, and not just the best on the market.

Why do you need metadata for video games?

The benefits of video game metadata come down to four outcomes, depending on how you use it.

Discovery. Players can only buy what they can find. To get the right game to the right individual, it is important to catalog these games properly using specialized video game data and metadata management practices. For example, if a customer is interested in Kingdom Come: Deliverance II, they would understand from the description that it is an open world RPG with a medieval setting. But if they wanted to understand to what extent the open world and RPG elements are present in the game, descriptive tags can show how strongly each one features. That additional layer of information helps the customer judge whether the game is right for them. Tags like these come from a consistent video game taxonomy, which is also what makes filters and recommendations behave the same way across a catalog.

Personalization. Recommendations and personalized home screens are only as good as what the system knows about each game. Detailed metadata lets them match players to games by genre, mechanics, themes and modes, not just by what other people bought.

Catalog operations. The most common problem faced by people working with video game data is that it is not 'clean', i.e. it is not organized and easy to understand. Conventionally sourced data would require a great deal of fact-checking and cleaning before you're sure it's employable. A consistent taxonomy and video game metadata schema give teams a structure to map their own game data to, so new providers and regions can be added without starting over.

Measurement. When every game has one identity, reporting and analytics count it once, whether it was recommended, played or advertised against, and a franchise's audience is not split across its editions.

Build trust in your game metadata

Organized game data and information, collected in a standardized manner, means that the data is immediately ready for use and its in-depth nature provides transparency that would have been difficult to achieve otherwise.

That matters more now that platforms use metadata to power AI search, conversational discovery and recommendations. These systems can only answer as well as the data underneath them. Scraped data carries over every source's disagreements, and AI-generated data fills gaps with answers that sound right but may not be, such as the wrong region's age rating or a game mode that was removed in an update.

Gameopedia's metadata is curated by a team of gaming experts who agree on every definition and use case, and it covers more than 285,000 games, editions and DLCs across 254 platforms. Gameopedia has a proven track record in delivering standardized metadata consistently.

Make your game metadata hold up across every provider

Most platforms already have metadata. The question is whether it still agrees with itself the next time you add a provider, enter a new region or rebuild search. When every source describes the same game differently, search results turn ambiguous, filters misfire and recommendations inherit the disagreement. Mapping those sources once is the easy part. Keeping the mapping current as providers change their feeds is the ongoing work.

Gameopedia Metadata, built by game experts, gives your catalog one consistent structure to map every source to, so discovery, recommendations and AI-powered search run on one unified catalog instead of several versions of it.
