I'd be willing to be a co-GM, but I'd rather not go for being the sole GM. I've played pretty much every game in the series except for 1, 2, and 3, so I know the setting pretty well. I also have a few general ideas for the setting and plot. And like Tentacle, I'd prefer to play antagonists, so if nothing else, I can still help play the villainous force if I don't become a co-GM.
