The best Nintendo game of the last two gen, for me, was Kid Icarus uprising. I really can't fault the quality of Nintendo 3ds' offering.
The Wii U had plenty of good games. However, many were small, low budget, games. They probably downsized the scale of development when they realised the system wasn't selling. I liked a lot of those little games but their budget of many meant they weren't as ambitious.
Of course, big budget games that stick to the tried and tested formula aren't ambitious either. I prefer sm3dw to galaxy, but because it follows sm3dl it's sticking to something that's already been tested rather than taking a risk.
Sometimes the more ambitious games aren't the best. Skyward sward and XCX and both worst of their franchises, to my mind (and I know some will disagree), but both were undeniably very ambitious and creative in their own way. I found neither as fun as Kirby's rainbow paintbrush or countless conventional and relatively unambitious indie platformers, but you could respect what they tried to do.
