Zero Sum Games is based in Portland, Oregon. We value games that are deep, rewarding, difficult, and fun. Our first official project, entitled StarDrive, is a hybrid between the turn-based space empire builders like Masters of Orion 2, and the top-down trading and exploring games like Escape Velocity. Begin the game in a small shuttlecraft without a penny to your name; end the game as the leader of an invincible space empire. We're very excited to begin sharing this game with the public. We expect a Q4 release, 2011.
