Yeah, that’s all fair. The idea that humans are more talented at powers is, of course, highlighted in the Pliocene saga in the first place, though that is used against them to some degree by the Tanu.I really dislike the speed of the transition, and the way humans turn out to be so damn special. Being human myself, I don’t mind if we turn out to be special in some way, but outstripping well-established spacefaring races in a matter of a couple of centuries just rubs me the wrong way. Plucky old humanity, my left buttcheek.
I much prefer the Pliocene exile books, where these problems are less evident. At least until Magneto shows up, doesn’t do much, and then is conquered by the power of wuv (retch).
In RPG terms it’s a little refreshing that humans get +1 psychic power rather than being adaptable or flexible or something.
