3Ds has been needing a 'Killer App' for some time now and this one might just be it. Maybe. It certainly has the characteristics: designed around the hardware of the device, huge hype, lots of production. Problem is that the control is so difficult it is physically painful for some. It also seems to lack an intriguing story, which matters to some. But I still love this game and I'm happy to own it. In short: I don't see it as a reason to buy a 3Ds, but people with a 3Ds have no reason not to get it.
