I played an intriguing game on the weekend, called Tomorrow. The world is in danger of over population, so its up to you (as a world superpower) and others to kill off enough of the population so you dont lose. So its cooperative in that sense, but if you dont all lose, then someone has to win by themselves - you score points depending on how many of your own people survive, and how many people survive in territories you control. Everyone starts with different numbers of their people tokens - like Russia has only 3, but each one is worth 5 points (if they survive...). While everyone has military and nukes, some countries will have more than others. Each country also has its own special power. Nukes are bad too - they count against you (in points, and they move the track the wrong way, towards the "everyone loses" point). I didnt quite know how to play this, its a negotiation game really, which I'm terrible at.
