What are some excellent games that remain excellent for a group of three?
So many multiplayer game lists include games that are only playable for 2 players (eg, It takes 2, portal 2). Best I could figure out in steam store search was to look for multiplayer games that aren't co-op, but this seems to remove many games that support 3 players.
Also since you did not mention playing remotely or not (although there are ways around that: parsec, steam remote play together...) almost any couch coop game: overcooked, moving out, unrailed...
Edit: all of those I cited have a online multiplayer mode I think, for overcooked the AYCE edition contains all of the first edition content but brings online MP amongst other things
