Though I voted against 5CC earlier, I am now in favor of it. It could make this game more challenging, and a high level of difficulty is something the demogame could use. I think we should play a game where winning isn't a foregone conclusion. I also voted for an Epic game (though preferably with a higher difficulty level).
I am not in favor of a MTDG. I do not know that splitting us into multiple teams would do anything to improve lack of participation, and if participation is lacking it could well be that teams will be controlled only by a very few people with little input from the other citizens, hence making it not democratic at all. Also, I like the single-player ideal: we are all one large team, and we're trying to win this one together. However, I would support an idea to start a MTDG on the side, separate from a single-player demogame, if we can get enough participation to make that feasible. It could be a replacement for the ill-fated MSDG and CISDG games.
