Well, I can't think of any other reasons other than the long player time, like 5 years. I mean I can help look for bugs and things, those can be spotted and reported on. Plus participating in the CBT is a good experience, you get to learn about the game and get to know people before the official comes out. Usually I'd no life and play the game, but summer is long gone... so about 7 hours can be contributed. - Thank you.
