Oh wow, that 3D Mario game. How exciting.
It's about priorities. It's insane that Nintendo plans to release 3D Mario before a Super Mario Bros. game. They are idiots.
For that reason I am doubtful that the launch lineup for N6 will include a really big game from Nintendo. They are probably trying to sell it on "Oh, look. Now we've got a touchscreen on our controller".
??? A 3D Mario is a big deal. Just because it's not 2D means that Nintendo is focusing more on the gimmick? What.
There's also Mario Kart 3DS. And besides that there's OoT.
