I typically play strategy games such as Age of Empires, Civilization, and Total War. I pick up a ton of games during the Steam Sales, but mostly for the single player. Crysis, Splinter Cell, Max Payne 3, etc. I also tend to play quite a bit of smaller, independent games such as Kerbal Space Program, Space Engineers, and Prison Architect. As of late, I've been trying to get into a few f2p shooters such as Hawken and Blacklight.
I don't currently have an xbox one, though I plan on purchasing one when Halo 5 comes along. I do play a bit on the 360, mostly Titan Fall, Grand Theft Auto V, Halo 4, and most of the Call of Duties.
I have, and now mostly play on, the PS4 and am currently playing through Watch_Dogs and Infamous: SS. I also have Battlefield 4, Killzone Shadow Fall, Madden 25, and AC IV.
