ButtonMasher: So in closing Portal 2 really is an amazing game. Valve uses the Source engine well and delivers a unique and challenging experience. Plus if you’re buying a new retail copy of the PS3 version you get a free PC/Mac Steam download of the game. Portal 2 really is a case of quality over quantity. While you’re playing it’s spectacular, hilarious and satisfying, but once it’s finished you’re left wanting more. Little replay value is the only real sore point here, but a perfect candidate for some decent DLC.
