If someone can tell me which direction to game specific communities i used to be part of (RimWorld, Souls games, Paradox games...) I'd be happy. Now I can only rely on discord.

And no, don't tell me to create the community and content myself. The audience isn't even high enough for discussing all games as a whole let alone specific games. This is what "let Lemmy stay small" crowd misses. Niche community can only be started as branch of (very) large community.
