Filter games by genre : request i have made to the support (what's your opinion ?)

useless, shitty devs abuse it anyway. When u click fps, u will find anime, and when u click platformer u will see puzzle.
Wishlist+group filters - enough for me. I don't use "recommended".

I don't think that could work being its own categories but a game filter would be pretty ingenuitive, that sounds like something a browser extension could do rather than the site itself though ¯\(ツ)/¯

It sounds like a good idea in my opinion but I don't know if it would be easily doable. I think the best option would be search parameters like "tag=strategy" as we can do to filter GA based on level or value.

They are already pulling a lot through Steam, I can't imagine it's cheap. Pulling genre wouldn't add much functionality for the effort expended or cost. Just hide stuff you don't want to enter for.

Pretty much useless as long as Portal is FPS, Pyre is sports, Speedrunners is racing and such, not to mention the troll / misguided tags on games.
