So my pick ups have been mostly games also on console.
The Witcher: 1 and 2 for about $8? OK!
Borderlands 2: Will try for $10.
Black Ops II: The online population is like Wii U levels of LOL, but it's easy to jump right into TDM games since there's always at least 1,000 people or so in that mode alone. Also like that I was able to just install the multiplayer and not bother with the story mode that I could give two fucks about. Playing with a 360 controller against all the KB/M users actually isn't as bad as I thought it would be. The craziest thing is playing with BOTH- using the controller for movement/knife/jumping and the mouse to aim actually kind of works.

Hotline Miami: This is way buggier than I would have thought on PC. Will probably just stick to playing it on PS3/Vita.
Saint's Row 2: Interested in replaying this with all the PC mods added.
Tomb Raider: All of the games for $17.50 is a steal! Might throw Lara Croft And The Guardian Of Light in there just to complete it, even though I have it on consoles.
Also have recently picked up Deus Ex Human Revolution, Lost Planet 2, Mark of the Ninja, Mortal Kombat, RE6, Sonic Generations, and Velvet Assassin. PC has completely replaced my 360 as the go-to "powerhouse console" at this point.
