Because Lionhead (the studio that develops Fable) is owned by Microsoft. You might as well ask why Super Mario Galaxy isn't going to be on the 360.DarkHuntress said:Why no Fable 3 on PS3? Course after the PS3 firmware update killed some games. I guess I can understand.
Anyway, it's cool that they're putting it on the PC, but it's really stupid to not allow the Collector's Edition. It's like, rather than having some nice incentive to buy the physical copy of the game, they're basically saying "Hey guys, go ahead and pirate this game, all you're missing-out on is GFWL which sucks anyway."
