I would like to see a team oriented puzzle mods where people have to cooperate to beat the other team. Maybe you have many players on a side who have to all work together to solve a big physics problem (oh boy...physics, multiplayer, lag oh my). Just to see people trying to communicate and cooperate would be a mess. Doubt it would be a popular thing, just something I'd like to see. Would be interesting from a gamer behavioral study point of view.
Sounds kinda like a tfc mod (i think it was), where players had to work together to get across an obstacle course
