You haven’t played Portal 2? You need to play Portal 2. The full review of the single player campaign comes later this week, but here’s a preview: without the co-op mode, purely based on the gameplay, writing, voice acting, and graphics of the single player mode, Portal 2 is excellent. Stephen Merchant and JK Simmons steal the show as Wheatley and Cave Johnson, the game is easily twice as long as the first Portal, and it’s even funnier and darker. For that experience alone, the game is worth the $50 it goes for on PC and $60 it goes for on PS3 and Xbox 360.

Well, went for $50/60. Amazon just dropped the price like a rock. If you want Portal 2 on PC, you can grab it for $30. If you want Portal 2 on Xbox 360 or PS3, you can grab it for $35.
