I've already voted for winner.
I'd also say that the following are things that went wrong:
1. We started this project at the same time as MA game. It would be better if we looked how it would turn out first.
2. Some confusion with game threads at start. Maybe it was insignificant, but still...
3. The time spent to set up wiki. I don't see that it added particularly to this project, but it took time and took still more while we learned something about wiki (the latter may still prove useful, but it was still time...)
Maybe some other things I've missed?
