Not excited at all. As owner of Mario Maker on Wii U there's nothing that makes me want to go out and buy this. Legend of Zelda Maker, now that would be a different story.
Slopes, vertical levels, new theme, and coming in June! So hyped for this. I expected this to be spaced out from New Super Mario Bros U Deluxe but I guess not.
Bringing in elements of 3D World is an awesome add.
Hopefully with a larger community than Wii U, we'll get more people making regular, well designed levels rather than 99% gimmick levels. That was my only problem with the original.
