@capybaraz #IronClaw / #JadeClaw, surely.

TSR's old #BuckRogersXXVc had several "human" species, but no single human species. As does its clone, Overlords of Dimension-25. (👍 👍 👍 )

Arguably you could count Palladium's TMNT/#AfterTheBomb, @ARBco 's #MutantsInTheNow , and @gibletblizzard 's #FeralRPG since humans exist but aren't really playable characters.
