I joined an ongoing PBW game as a replacement player and... well, most other races hail from gas giants. Is there an advantage in being able to colonize large planets only, or is this offset by the fact that large planets are rarer than small ones?
I suspect that in multiplayer games there could be a small drawback: in this particular game I happen to have an ice-based race and I'm happily colonizing the galaxy while the gas empires fight over colonization rights...
