I think the "Tilt n' Tumble" gimmick has been done to death already and that detracts a fair amount from the game.
Koroinpa and Mercury meltdown have also done it and it's wearing thin now.
I'm sure that after Ghost Squad, RE:UC and some of the other lightgun games hit, we'll declare those "done to death" as well, though the Wii is still the best platform for them.
"I mean, c'mon, Viva Pinata, a game with massive marketing, didn't sell worth a damn to the "sophisticated" 360 audience, despite near-universal praise--is that a sign that 360 owners are a bunch of casual ignoramuses that can't get their heads around a 'gardening' sim? Of course not. So let's please stop trying to micro-analyze one game out of hundreds and using it as the poster child for why good, non-1st party, games can't sell on Wii. (Everyone frequenting this site knows this is nonsense, and yet some of you just can't let it go because it's the only scab you have left to pick at after all your other "Wii will phail1!!1" straw men arguments have been put to the torch.)" - exindguy on Boom Blocks
