Only if it's ported to XBLA, Steam and PS Network.
But if not then never, cause I don't want to buy a new phone in order to enjoy more Fallout.
if they made enough money off of it I'm sure they would. hell, that friggen' angry birds game can be downloaded as a PS mini off of the PSN, I don't know about XBL and Steam, but I was surprised to wake up one morning and see that.
but yeah, it definetly wouldn't be fair to others, having to put up with Apples BS just because of a Fallout game. it's bad enough there are exclusivity deals, a hardware-specific game would have the Fallout community rioting in the streets as if they had announced "the game that shall not be spoken of 2" is being released as the next Fallout....
