So I just got the Orange Box for the 360 and will be playing Team Fortress 2 for anyone who wants to log in and play. Gamer tag is KrookedNelson. This post was really about the game portal that comes with the Orange Box as well. Great puzzle game, and has a very "Independent Film" feel in a video game. Here is a lowbudget flash version if you want a small taste. The actualy game is in 3D and much more fun.
