Zelda is bigger.. If you had put a Fable game on Wii after many core gamers had shelved the system it wouldn't have come close to the sales of Skyward Sword. Zelda sells well despite the console it's on wheras Fable requires an install base of hungry core gaming buying games in order to acheive sales success.
Try releasing a Fable game years later and competing with the 3ds numbers on OOT.
