So hotseat mode was one of the bigger selling points of this game. While I wish it had the ease of the SP games from matrix, Im glad to see it was even included at all. I know when you do a hotseat game you have to issue a challenge and then go back and accept that challenge. Problem is is that when I issue it, it doesn't show up for me to accept, ie., no hotseat mode. Any ideas or help? Thank you.
