Doesn't give me that option, only able to play against the User or to just sim the game. I've only been able to play against the CPU if the team doesn't have a User controlled GM yet.
When you request a game notice how it says "enable cpu" or whatever it says, your opponent for that week has to turn that on otherwise you cannot play until they are on. It sucks, but considering the difficulty of the CPU, it might be a good thing(for me).\
Oh I know that, I just like to be able to play the games myself. I'm sure there are times when I'm not online where my opponents want to play me as well, just the nature of it.
I find User vs User games to be much more enjoyable, but they're harder to find. I'm Montreal, so if any of you guys have me on your schedule, hit me up with a PM or a message on XBL and I'll be more than happy to play you guys.
