Today Portal 
got released and I've finished the main storyline already.
What I like about that mind twisting game you ask? Well... absolutely everything! The idea is awesome (although it's not from Valve), the graphics are nice and the sarcastic robot voice is stunning and funny as hell!
But beating the story mode is not the whole game. You'll get bonus missions like solving the played rooms as fast as possible or with with the least portals for example. There are also some more difficult levels unlocked you may test your skills at.
Additionally it seems like the bonus mission part can be easily enhanced with downloadable level packages so prepare for even more portal fun.

There is also a complete chapter 11 chamber 19 video available, including the boss fight and the awesome credits here.
