You can already play Evony on your PS3. But it takes a while to login and it will kick you out after a certain amount of time (I think like 10-20mins...)

As for WoW and Runescape, WoW is designed for PCs, and cant be ported over especially with all the spells and shiz that require hotkeys, Runescape is a silly game and I won't comment on it lol
