What other MMO and Single Player games do you play?

Jahrakajin: Besides Ships and Tanks I played WoW on a vanilla server but stopped cause got bored after our Guild reached Naxx.

Other games would be:
Crusader Kings 2 Cossacks 3 The Witcher 2 (in progress) Don't Starve Together
Jagged Alliance 2 (1.13 patch)
S.T.A.L.K.E.R. series
My backlog however is so huge I'm not sure if I'll manage to even finish half the games by the end of the year...for example I have the Witcher 3 since late 2015 and didn't even have the time to install it yet
