I want a simple collaborative game platform that can be used to generate discussion between two teams of students who are given a particular problem to solve. I would ideally like each team to be given a series of positive cards, negative cards and some sort of bridging cards that can allow them to move from a negative opinion to a positive one. The game would also have a system for rankings, leader points, experience points based on participants' contribution to the solution as the game progresses i.e. played most bridging cards and less negative cards.
The idea behind the game is to get students to be able to work towards a solution with limited resources and to work with people who might not share your views. The game should be modern looking, maybe flash, have a cool interface. some sort of chat feature/social part.
