A combination of higher O2 and lower gravity could work. That way they'd be able to function from both a biochemical and physical point of view.

Lower G would mess up the atmospheric gradients and pressures/concentrations though, and the O2 concentration would be limited.

I doubt the game creators put that much scientific thought into it. ;)
