Back in my day we used to play games in the same room as each other :p. Competitive gaming is a lot of fun but there is something about teaming up with friends for a common goal that is a unique experience. For this contest let me know your favorite co-op game. It can be old or new but it has to be you on the same team as your friends. No team competitions for this one either.
I am going to pick left 4 dead, that game was great. I hope they make a 3rd one.
Same rules, a bunch of upvotes as prizes.
