I have played and completed Super Mario 3D World and Mario Kart 8. Super Mario Bros. on Smart phone will help Wii U and 3DS, since it makes Nintendo richer. It would help fund Mario Kart 9, Super Mario 3D World 2, and Super Smash Bros. 5 on Wii U. The New 3DS was released this year so Nintendo hardware stays relevant. Sony publish a Xperia running Android, but it failed. Playstation Portable and Playstation Vita were lagging far behind DS and 3DS sales. A "Phoneboy" with 4G LTE would work as long as it runs Android. A Phoneboy running quad core CPUs and 4 GB of RAM.
