Yeah Portal 2 is my fav game of the year so far! I would give it a 9.5/10.
@Fadetoone - I will agree with you that a lot of the challenge did come from finding hidden areas that you needed to reach first to setup portals, hit a switch or paint the ground with gel before you could solve some puzzles.
I think Portal 1 Single Player was easier though, except for some of the special challenge maps after you beat the game.
