Hmm...well, I occasionally play a weird/cool game called Improbable Island. It's all text-based so you can play from pretty much anywhere. leaves it all to your imagination.
Roleplaying is wide open, since the game is designed that you can invent and roleplay anything. I have my character with horns, wings, and 3 inch thick fingers so he can barely pick up anything.

Best part is that you level from 1 to 15, then kill a boss, then get respawned as a level 1 - but with different perks like more attack and defense, hit points, etc. You can also switch races between boss kills.
If text-based isn't your thing, then I'm not sure as I stuck with SRO, and GW2 isn't out yet
