I still don't understand the mindset of serious beta testers. On one hand, if their oppinions could be used to change the game in some aspect, that would be fun, but since the game is almost out, this is usually not the case.
Meanwhile beta testers spend so much of their own *free* time downloading, installing, and trying to get buggy, un-finished software running on their machine.
What is the incentive? You will be a month or so better than me? Does that really matter so much to them?
