I'm trying to find a kind of game, but I'm not sure if anything like it exists. It's for a team-building excercise at work if you want to know the context. Do you know there is anything out there that matches these criteria:
Can be played over a network or through a browser
Teams of X people, working towards a common score for that team
Multiple teams (6+) competing against each other for the highest score.
Free (or really cheap)
Ideally something that can be played and worked on over a long period of time (days)
I was thinking about that Icarium game I've seen people talk about in G&T but I haven't tried it out yet. The idea is to have some kind of common goal that members within the team can discuss and work on together. I think Icarium is each person for himself -- or can you group multiple players into a team?
