Card games, board games, people have 'modded' in a ton of different games to the game..... OK that sentence is more confusing than it needs to be.
Table top simulator has mods - I think it's surprisingly easy to make a mod for it, they try to have it easy to work with. Mods themselves are board games. I think I've seen stuff like Betrayal at House On The Hill, Apples to Apples style stuff, etc. Just need to get Tabletop sim itself, and then everyone gets the same mods that they want to play. I'm totally up for joining!
