5/5, will play again

Thus endeth the review.

Well, kinda. I guess I should elaborate a bit.

Portal is excellent. Its a fantastic concept, well executed, and at a beautiful dificulty curve. Then its over, with a wonderful feeling of satisfaction.

Although I've not played the bonus challenge maps, I have played through the commentary, which took about an hour, because the second time through you know all the puzzle solutions, but it was an interesting listen.

And all this after deciding to buy the game about midday, downloading it over my (not particularly nippy) connection, and solving it before midnight. Now for user created maps!
