I agree. Lately their games feel very uninspired. Mario Party, Ultra Smash, Mario and Luigi/Paper Mario Crossover, the Wii U to 3D ports, Pikmin 3DS, and likely others I missed just feel so.... meh. They're just being too safe now. I wish they would try their hand with new ideas or at least add in new characters to existing series.

Hopefully they're saving the good stuff for the NX and this fluff is just to hold things over.

Funny because I think on Wii U alone we have had...
The best Mario Kart in the franchise
The best Smash Bros
The best Donkey Kong
The best Pikmin
A fantastic 3D Mario
Mario Maker
Great new IP in Splatoon, Wonderful 101, Captain Toad and Lego City Undercover
AAA games like Xenoblade and Bayonetta 2
Crossovers- Pokken, Hyrule Warriors, Tokyo Mirage.

3DS is also full of great stuff. I personally have had no problem with the quality of Nintendo games this gen, and even think they have shown some ambition. Sure there are some suspect games to come out too, but on the whole I think Nintendo have done well on their platforms this gen.

Mario Kart 7 and 3D Land were bad ass in my opinion.  NSMB2 was a joke due to insane amount of coins you are bombarded with but had a few difficult stages (not many). 

I have already lost hope

I think the quality is a little forgotten due to the recent shit stain they left with their shovelware games like AC:Amiibo Festival.  I'm happy with my 3DS and Wii U purchase myself.  Could it have been better? Sure but it was good enough for me to not feel one bit bad of my purchase.

Why would they put huge amibitious titles on the 3DS when they have a new console releasing in 6 months? Come on... Like really?

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.

What huge ambitious titles?

Safe/conservative/lazy games just don't inspire and impress the way that ambitious ones do.

A decade from now, I'll still be in awe of Mario Galaxy; of its epic sense of adventure, its sweeping soundtrack, its wondrous abstract levels, its celestial starscapes. 3D World, on the other hand, will be long forgotten.

3D is a amazing multiplayer adventure. is the better multiplayer experience a mario plataformer ever deliver.
as not so ambicious as galaxy, we needed this game.
