Race for the Galaxy is - together with the Robot from the Gathering Storm expansion - a really cool solo game. I have never played the game in multiplayer, only alone against the Robot (and 1 or 2 times against the Keldon AI). And so far, I have only lost. But the way to losing was always exciting. A bit of a shame is that the Robot really builds up high pressure and you therefore really have a race with him: one of the main goals must be to end the game as quickly as possible and score more victory points than the Robot. You can't afford great development work here, every turn must bring victory points and bring about the end of the game (either collect direct victory points or - usually better - bring cards into your own display). If you like science fiction themes and are looking for a solid solo experience, I can really recommend this. However, it's not quite cheap, as you need both the main game and the expansion.
