Star Wars: The Clone Wars, an exciting game based on the mechanics of Pandemic: a cooperative game where each player must counter a threat that is multiplying everywhere. In Pandemic, you play scientists who must combat a virus (hence the name), in this Star Wars game, you play Jedi who must counter a droid invasion.
They quickly grasped the concept and had no problem coordinating, although, I must admit, I cheated a little in their favor to avoid a crushing defeat mid-game. :)
A special shout-out to Binh Minh, who didn't know Star Wars. But when I say he "didn't know", I don't mean he didn't know every detail, down to the titles of each Sith, no, I mean he didn't know Star Wars at all, as a whole. Which is utterly unacceptable, wouldn't you agree?
I have all the films in French if you'd like. :)
