I know it's late, but the AI is not another player, and it's not checkers. It's a video game that people want to play and enjoy. It doesn't hurt me in anyway, I have completed it many times, but other people may not have as much time to devote. They should be able to play it that way. Think about it.. It's co-op! It doesn't hurt anyone and I can see where others can exploit, but so what?! They are only cheating themselves. I just think that it's stupid to give us a pizza and start to pull all the toppings that we paid for off.
