My fellow escapists, I'm in the process of researching material for a paper dealing with TF2 and built environments, as well as the community that surrounds the game, and I need to know: does the PC version have more dev. commentary in it? Has more been released through the updates? I need to know, because I need to know if it's imperative for me to buy it on PC for the project or not (I was originally just going to make do with the 360 version.)
