I don't know if the thumbs is for my post, or the 3DS, or the iOS version with no buttons... Perhaps you're a fanboi who can't see fault with iOS devices and think that any version on an iPhone is better than any version created ever cos it's magical and revolutionary
But actually, in part, yes - do additional buttons, real or not, provide something better than the iOS version delivers?
Does the new stick thing or D-pad on the 3DS work better than the iPhone screen? They'd provide more feedback because you would know it was being pushed and the character would be doing something, rather than mashing at the screen with sausage thumbs like I do and get annoyed when Ryu's not chucking out a fireball across my iPhone screen cos my thumb's momentarily in the wrong place.
Perhaps the graphics are better, but I doubt it looking at the 3DS screen shots.
There's loads of extra characters in the 3DS version, so does that add to replayability over the iOS version?
Loads of different fighting backgrounds. How is the bottom screen used? What different, and I assume more, game modes are there... Bear in mind that the comparison is between a version of a game designed to be played on a gaming system, not a version of a game to be played on a phone that also plays games.
All of these things add up to value-for-money. All these things considered, is it 10 times better than the iOS version? If it isn't 10 times better then parents like me should perhaps think of getting an iPod for a Christmas present for our fledglings instead of the latest mobile gaming hardware
