Race for the Galaxy. The first time against the Gathering Storm AI - wow. Completely crushed - 32 to something around 50. Even though I had two 6-point Developments out - but my worlds were relatively small, so not many points, and the robot had 18 VP chips and 3 6-point Developments and another stack of worlds and Developments. No chance for me. But after some initial stuttering in the game, it ran quite smoothly afterwards - definitely fun on paper.
