I'm not quite sure why everyone who plays this game insists on spoiling it afterwards. I heard the same spoiler line repeated by at least three people I know and several other sources online. Hell, they literally print it on t-shirts.

It was a pretty good three hours of gameplay. The writing is quite amusing and the gameplay is interesting. The puzzles were definitely good puzzles -- and consistently so -- but they got a little repetitive. I don't feel particularly compelled to play the advanced levels right now, but might some other time. Edit: Played the advanced levels. They seemed to require better precision and reflexes rather than more thought. Oh well.

Not sure if I'd say it deserves all the hype it gets.

I ended up having to play on my MacBook Pro as my desktop machine's audio driver apparently hates Portal. It starts using 20% of CPU in the kernel, makes the game choppy, and makes the sound click a lot. The MacBook handled it just fine, though. I'm pretty fed up with PC gaming at this point. Consoles just work, no questions asked. PCs need you to fuck around with drivers and video settings and sometimes still don't work.
