While today's Nintendo Direct didn't provide much info on Mario-themed games, it did offer a couple of plumber-themed tidbits for Super Smash Bros. and Rayman Legends.
Starting with SSB, Luigi became the 14th officially confirmed character for the 3DS and Wii U brawler. The younger Mario sibling appeared in all the prior Smash Bros games, so it would have been a shock if he wasn't featured in next year's entry.
Secondly, Nintendo revealed Rayman Legends will include Mario & Luigi skins on the Wii U. Rayman can don Mario's red garb, while Globox can become glamorous in green. Ubisoft's press release notes the costumes can be unlocked after 20 minutes of gameplay.
The Wii U version is, for certain reasons, not the only one coming to retail shelves next month. It'll be joined there by Xbox 360, PS3, PC, and Vita siblings when the game launches in North America on September 3, and in Europe a little earlier on August 30.
