I don't think the focus here should be on the fact that the actress in the Japanese ad is attractive (which she is), but the fact that the NA ads limit their target to kids and are often generic and unimaginative. The Pikmin 3 commercial comparison that Soundwave showed earlier in the thread is a prime example of this: The UK ad is incredibly appealing, the NA ad is lame.
Then there's that great ad for Wii Sports Club featuring Andre Agassi for the UK which I'm sure we'll never see here in the States - same way we never got those great UK commercials for Zelda OoT3D that featured Robin and Zelda Williams.
The SM3DW ad for NA is ok at least, but if that's the direction they wanted to go it would have been better suited showing a family (adults and kids/teens) playing together, IMO.
Still, beggars can't be choosers I guess. At least NA is actually getting a TV spot for SM3DW unlike The Wonderful 101...
