We're Doomed!

The world is coming to an end. You, the most powerful leaders in the world, have only fifteen minutes to build an escape rocket and leave this doomed planet. With limited time to build the rocket, it might not be big enough for everyone. You have to work together. However, in the end, only the most influential survive. Contribute resources to build the rocket, but gain influence to claim a seat... possibly one that someone else built.
