Heh, I was going to bring up the case that someone is good at two areas of game design too. I suppose dividing by team role is a way to make more balanced teams, but what if there are 5 coders, 5 musicians, 8 story writers and 3 artists? Such a situation might come up,and it'll be difficult to divide this way. One of the challenges of a team challenge was to work with what was available, if there were two writer's on one team, and 2 artist on another, different areas of these teams games might have different quality. Then again, more than one coder on a team isn't useful, it's very difficult to pass coding from one to the other, because of style and other issues.
forget it, I'm just rambling. I'm sure whatever the organisator tries will work eventually.
There will be a theme/rules, yes?
