I don't think "small" core titles sell on the Wii period.
If you're going to do a core centric type of game on the Wii ... you better bring it. It better be something like Zelda or Monster Hunter Tri. I think a game like Final Fantasy: Crystal Bearers for instance will do OK, but stuff like Little King Story ... not so much unfortunately.
On all systems though there really aren't a lot of "smaller scale/budget" games doing well unless they're party games.
