I just want to say that we don't need two New Super Mario Bros. games in the span of four months. I just want to say they should look more different. I just want to be a grouch, but, actually... this game looks lovely!
Is your heart not melted yet?
Then watch this gameplay demo.
Man, all it takes to win me over again is a Mario with a world map. What can I say?
This is a "launch window" game, so it'll be out between the Wii U launch and the end of March 2013.
UPDATE: Actually, this is confirmed for launch day, so November 18 it is!
