I certainly have categories, but not quite as neat. It’s a crazy mix of genre and vibes, and many are in multiple categories.

Finished, RPGs, VN and anime, With Friends Only, Trash, Garbage, Need to finish, low interest, party games, roguelikes, and a few more that I can’t remember right now.

I also have a dynamic category for filtering with a specific steam friend when we’re figuring out what to play, that filters for multiplayer tags and that they also own. Plus, removed the trash that no one wants to play.
