I thought that the Orange Box was going to be my 360 game of the year, but after only playing Bioshock for 40 minutes, Orange Box has fallen.

Portal is great, and so is Half Life 2, but I can't play TF2 without Xbox Live, and Ep 1 & 2 need Half Life 2 to be played first, so a little disappointing.

Rapture is one of the most immersive worlds ever, and it plays like a dream. It has also beaten off Call of Duty 2 as my favorite 360 game.
