But gravity in Spore is nothing like the real world. The planets are very small. From appearances they seem to be on the order of a few square miles of surface area at most. Any "planet" that size would be an asteroid in the real world. Its gravity would be negligible.
Still, I see your point. If we assume that gravity is multiplied by some factor in the Spore universe (which is likely exactly what they've done), then it should scale like gravity does in the real world.
However, first of all, this is a game. They don't have to follow the real laws of physics. Secondly, not all planets are necessarily equally dense. The various elements vary enormously in their mass, and a planet comprised entirely of, say, gold, would have a much higher gravity than a planet of the same size comprised entirely of carbon. Of course, those are extremes, and no such planets could ever exist (except possibly in a game
), but the distribution of elements do vary a lot between planets. As such, gravity is not only a question of volume (or radius, if you will), but also of density.

Indeed. But since Spore does take evolution into account, a species could conceivably, over time, adapt to much higher gravities than that of the planet they originated on.
Actually, that would be pretty cool. Imagine evolving a race for immense strength, by moving them to a planet with higher gravity, letting them evolve there for a while, then moving them again to a planet with still higher gravity, and so on.

Again, only assuming that the amount of atmosphere is the same. It needn't be.
Look at Venus. It has a surface gravity of 0.904g. However, its surface pressure is around 90 bar. The explanation is simple: Venus has a lot more atmosphere than Earth does, and it weighs considerably more (the atmosphere, not the planet).
