I'd probably play modern war games if it weren't for the AI soldiers on my team straying away from modern military tactics by running directly into my line of fire every time I pull the trigger, and the fact that every time they do that, they never tell me they want to advance. Got really old in the first Modern Warfare, so I uninstalled it and never went back.
Mostly been playing coop games with a buddy lately, like Army of Two and Left 4 Dead. Played Space Marine, Dead Island, and Fallout New Vegas a bunch lately too.
