HECK YEAH!!!! I've been up all night playing Portal 2. Best. Game. EVER!!! Far better than Portal 1 (and that's really saying something). The level design is perfect, the environment is perfect, it's THE PERFECT GAME!!! I would still be playing it, but the whole school thing is getting in my way. Fortunately, it's a short day (I'm done at 11:00), so it's back to awesomeness in a few hours.
