I'm up for most of the things mentioned here. I think Gmod, Left 4 Dead 2, Killing Floor, Risk of Rain, Battlefield games, Guns of Icarus Online work. Basically anything that doesn't become a huge timesink - ideally something that can be played on a game-to-game basis without having to worry about progression. If a lv 20 dude has to play with lv 1 people and a good balancing system isn't implemented, it won't really work. I'm up for a variety of RTS games as well, be it Age of Empires II HD, Battle Realms, Rise of Nations/Legends, any Command & Conquer game, Warhammer 40k games and so on. Things like Broforce and Expendabros should work too.
List of things that I think will work:
Gmod
Left 4 Dead 2
Killing Floor
Risk of Rain
Battlefield games
Unreal Tournament games
Guns of Icarus Online
Broforce
Expendabros
BattleBlock Theater
Castle Crashers
Magicka
Awesomenauts(as close to a MOBA as I'll get)
Saints Row: The Third and IV(scrath that, max 2 player supported"
Serious Sam games
RTS:
Age of Empires II HD
Battle Realms
Rise of Nations/Legends
Commad & Conquer games
Warhammer 40k games
P.S: Editing this as I recall other games that fit the criteria.
