Why exactly are we fighting?

Season 2 of Red vs Blue is set to premier sometime this weekend. The makers aren’t saying exactly when they will post the episode. I assume this is an attempt to get people to repeatedly vist the site and tempt them into buying the sesaon 1 DVD (it worked on me). Season 1 (Blood Gulch Chronicles) took best film and best writing at the 2003 Machinima Festival.
