The Super Mario Bros. with Luigi I bought in a bundle with the WiiU.
There are so far my only games for this console.
(Reason for buying was Mario Kart 8, which is already pre-ordered)
The graphics are so beautiful that Level Design plus spiced wonderful and the music is reminiscent of the good old Mario music, but a lot.
What I also liked a lot, it's fun but not so extremely addictive.
I play it than an hour, am happy and satisfied afterwards.
