The Future of the World?

Sure as heck we do! In fact, in most fantasy settings i have to constantly wonder why humans *don't* dominate everyone else, (say, in the ever-popular Forgotten Realms) Dominions is actually a nice exception to the rule. Ok, the complete undead are out since they kind of obviously win in any fantasy setting but other than that, there are still races that should outcompete humans in the dominions world. C'tis is a likely candidate, due to sheer population volume. (Laying eggs really is more efficient to produce cannon fod.., uh, offspring) But R'lyeh also look good.
Standars elves as seen in a hundred fantasy settings? Pshaw, living a few hundred years while still maintainting a constant population size means a birthrate far too low to compensate even for a single major war.
