Just to put it out there - COD Ghosts, GTA Online, MLB 12, and Minecraft. I don't play a lot of Minecraft but I have a feeling it'd be more fun online.
I've slowed down on GTA for the time being, but if we got a League Crew going, I know someone set up a good website to track Crew Wars, since R* seems to have dropped the ball on DLC and Turf Wars.
