Portal 2 despite only having 3 major voice actors has by far some of the best voice over in a game I've ever seen, there wasn't a single level in single player i didn't laugh at. pair that with progressive levels that get more difficult as you proceed and co-op that is just as successful. Portal 2 is a must get game of the year candidate!
this game was one of the greatest games i ever played. this game keeps you thinking and never gets boring. I especially love the robot voices, glAdos and the turrets. The graphics are truly amazing and stunning, a must buy for everyone. sucks that psn is down, cant play online.
