Ok, so I finally got The Orange Box (I know, I know, I'm 3 years late, whatever. I have a Mac, portal was just released for it yesterday) and Portal blew my f***ing MIND. Of course, a large amount of the story had been spoiled for me, but I had never watched a YouTube video of the ending, never seen actual gameplay until a few weeks ago. I avoided most of the whole "The cake is a lie" thing, due to not having any friends who play PC games, so that didn't piss me off too much. The only complaint I really had was how long the last level was. Admittedly, I could have stopped at any time, but I knew I was almost done and I wanted to get to the balls-tighteningly fantastic ending. Anyway, this game is great, and the rest of the Orange Box should be fun too when it's finally released for Mac...
