Super Mario Bros: Starlight is a game for the WiiU. It's a 2D Mario game, but has story progression similar to the RPGs.
Since the events of Paper Mario, Bowser's troops have been attempting to replicate the Star Rod. Recently, they've made a breakthrough. However, the replica can't be powered by a Power Star. It harnesses the power of a Ztar. With his new powers, Bowser shattered the Star Rod and launched an invasion on the Mushroom Kingdom. His airships attacked the castle from above, While Bowser's foot soldiers marched in the castle. Bowser waved the Ztar Rod and teleported Peach to him. He also shot beams of dark energy, which knocked Mario, Luigi, and the two Toads unconcious. When they awoke, the princess was gone! Lying next to them was a tiny Luma. It woke up and introduced himself as Lumino, who was sent from the stars to alert the legendary Mario to save his 'Mama', which was Rosalina. Lumino told the heroes that to save the princesses and stop Bowser, they must find the seven scattered pieces of the Star Rod to counteract the Ztar Rod. With that in mind, Mario and co. ran off to save Peach and Rosalina.

World 2: Dusty Dunes -Oh boy! The second world is desert themed again! Some of the levels take place in ancient ruins. You can find Dry Bones in some levels, but Pokeys will be the most common type of dangerous fauna.
World 3: Sparkling Ocean -This world is filled with aquatic enemies such as Cheep Cheeps and Bloopers. The frog suit is going to be useful for diving in the water levels. Beware of Boss Bass, because if it eats you, you'll be sleeping with the fishes!
