Interactive game

Just got back from Amsterdam and I was given my first project. With 3 other people I am going to produce an interactive game. The game doesn't have any limits thinking of platform. You could make a game for the ipod for example, the only restrictions it has is that the game must be an interactive game that can be played by more than just one person. It needs to be a "gezelligheidsspel" what we call it over here in The Netherlands. For tomorrow we need a team name and a logo, so I have enough to do today.
