What's your pick?

Out of the ones I've seen with my own eyes, 3D World.

WWHD cause its just so damn good

But Mario 3d World for all the serious people out there

3d world followed by rayman legends

SM3DW, its simple but has a great attention to detail and has these little effects that put it over the top, ex the rain drops on the screen.

Gotta be 3D world, although one could argue that WWHD is artistically prettier. But the models in 3DW are flawless...they look like real objects. And the rain, water and lighting are state of the art.

Yeah, I loved the rain effects, how water flowed down vertical surfaces, splashed up as you ran, and made characters look drenched.

Its got to be Mario 3D world, followed by Windwaker HD and Pikmin 3. May i also add that the lighting effects in Zombi U are top notch too, the whole look of the game suits the dark atmosphere.

Don't have a Wii U yet so I haven't seen any in person, but Pikmin looks the best to me from the videos I've seen. Not crazy about SM3DW's art style, but it does seem technically impressive.

As a whole, SM3DW easily so far. Yes, those rain levels are GORGEOUS!

That being said, there are moments and specific things in WWHD and Pikmin 3 that take my breath away graphically. Wind Waker's "tall grass" and the bloom when out on Outset Island and the use of light and shadow to simulate the cool shade is just really well done. Pikmin 3...the water. "Nuff said.

In April or May, my answer will be different. I NEVER expected that I'd say this at any point of any Nintendo system's life, but a Mario Kart will likely be the best looking Wii U game by a mile when it comes out. Mario Kart 8.
