For games and platforms there could be an icon imagem, of small size, which could be used as a visualization flair on the website and also as a data point for the API, as applications could use them to their UIs.

On a number of company pages, the game list does not appear, and games associated with the company can only be viewed within the timeline element (which does not display games without a release date, and is slow to reflect updates). This issue seems prevalent among company pages with relatively few games, although that might not be the direct cause.

Examples:
https://www.igdb.com/companies/cecile-richard
https://www.igdb.com/companies/d3t-limited
https://www.igdb.com/companies/kitty-horrorshow
https://www.igdb.com/companies/michael-lutz
https://www.igdb.com/companies/remy-trasevol-dog-devaux
https://www.igdb.com/companies/sophie-houlden

Can't receive updated data for this game through the API.

Not a fan personally, but it might be worth documenting with a simple Yes/No Checkbox.

Ex. Jak & Daxter Collection PS3, Resistance 3, Uncharted 3, etc.

Iruna Online is a mobile game that been out over 8years since 2013 and Iruna online has it in the twitch game categories but has no box art at all and I have a perfect box art for it but I don't know how to apply it or upload it to you, please apply a box art for Iruna Online cuz it doesn't have one at all

When you filter by alphabetical order or Rating or release date the list is different but the number of pages does not change.
An example is PS1 since the alphabetical order A - Z page 54 ends up in the letter D and from Z - A page 54 ends up in the S. Which means that games with initials E to R do not appear in alphabetical order however in other orders they appear and others do not Final Fantasy VII appears in the order by Rating but not by Release Date or Alphabetical

Arcade or console games usually have an internal serial
e.g. http://redump.org/discs/system/naomi/

And different port of the same game would have its unique serial on different platforms

I'm currently working on a project where any (eventual) users of my app will (with their consent) be parsing their game libraries and providing data where it's missing in igdb, I'd like to be able to post this data via my app to your database.

Obviously, I'm not expecting to be able to post directly, but the ability to log contribution requests via POST commands would be good.

Allow fetching detail rating breakdowns; ie the data that drives the below image on the website;

https://www.igdb.com/games/horizon-zero-dawn-complete-edition/rating_breakdown.svg

The level of detail presented in the chart is sufficient, ie, number of ratings at each level of ratings, example output below;

{
"ratings": [
{
"ratingname": "Superb",
"ratingcount": 10,
"ratingvalue": 10
},
{
"ratingname": "Great",
"ratingcount": 100,
"ratingvalue": 9
},
{
"ratingname": "Good",
"ratingcount": 1000,
"ratingvalue": 8
},
{
"ratingname": "etc",
"ratingcount": 120,
"ratingvalue": 7
}
]
}

Other note: underscores for italic formatting is annoying. :)

Just like we have websites like Wikipedia and Wikia, Google Arts and Culture also have info pertaining to games.

Example: https://artsandculture.google.com/asset/video-game-super-nintendo-super-mario-world-nintendo/aQG4PR61zCQHRA?hl=en&avm=4

ELSPA was the rating system used in EU before the PEGI system replaced it.

Degrees of ratings can be found here:

While this may need a bit of oversight, there are some extremely good examples of documentaries or historical breakdowns of game releases and/or even controversies. These are topics that are not generally covered in the official trailers or dev logs, or even gameplay videos. These videos can lay out a history of why some titles are cancelled, or overhauled, or have a troubled history outside of the game itself.

Examples:

• Noclip's FFXIV 1.0 to A Realm Reborn Documentary
  https://youtu.be/Xs0yQKI7Yw4

• What Happun? series
  https://youtu.be/x3JYev-4lOc

• Top Hat Gaming: Renegade/River City Ransom/Kunio-kun

If you make a version, or port of the game, the majortiy of things like categorization, series, cover are likely to be the same. It actually deters people from creating new versions by not providing a function like this as a template

I'm not personally a fan of these titles, but I feel it would be helpful if we had a more high level flag for these entries. I feel this would have several benefits over a simple keyword, such as filtering search if you want to include or omit these titles, or on the Twitch side that would serve as an instant highlight in the categories that would appear next to the game itself.

https://api.igdb.com/v4/age_rating_content_descriptions has some unkown category enums like 58 and 50 for the ids, 13505 and 13506

In these months I thought and realized an MVP about a IGDB/Twitch app in which an user can follow game-events (like E3) and add presented games to their wishlist or library (user can search them manually later also). Obviously I'm using the igdb API to fetch game info. how can I share the idea with igdb/twitch? thanks

Is it possible to add Metacritic, PC Gamer and IGN review scores to every game?
