Yeah, it's sort of a shame that so many fantasy races have to stick to the upright, two arms, two legs, one head base unit, and just toy with the decorations really.
Give a gelatinous cube telekinesis and it could live, I'm sure, and I imagine it'd breed by splitting like ameoba.
Certainly from playing WOW a while I've seen almost all the races in game stem from 'man+animal=new race' and while not particularly imaginative in concept, I think they're done very well in game, especially blizzard's habit of affixing a real world racial idea to them.
I forget the name, but the new anthropomorphic walrus based race in the icy wastes of the Borean Tundra, are obviously based around Eskimo (can we still say that? I for the life of me can't see how it's offensive or how Inuit is better...but that's a whole new topic.)
The trolls are Jamaican, the Draenei, Russian, the Tauren are 'Native American' (Seems I'm fine with that but can't naturally take on board Inuit, I guess because it's just not used so much.),Dwarves have a touch of the Scottish about them, (If anyone should be mad its them, always stuck with the ginger alcoholic psychopath image!) and even the Consortium, I forget the race name, but they're beings of pure energy, but they wrap themselves in bandages 'mummy' style, so get to be humanoid in form too.
One that did break with convention are the Naruu, who are just geometrical patterns of light in the air, tho I always thought they looked made of brightly lit glass or crystal, but at least they're not a typical humanoid form.
