I'm curious.
In the games list, or in any series, you can filter the search by "Show unofficial releases".

I noticed that some of the games I moderate are "official", and some are not (all are web games by the way).
I also didn't mentioned anything about being "official" when I requested the games.

Okay, and how do you explain some of my "unofficial" games?
Or in other question, how exactly a game here becomes official?

When it's an original game and not a fangame or a mod

@Oreo321 mods dislike web games and they hide them with this trick.
You can not request to remove the web game tag or make them official.
