Finally watching the Nintendo E3 videos. Love the idea of Miis in Super Smash Brothers. Make a Chun Li Mii, and suddenly you have SF vs Nintendo. Or even MK. :)
Hyrule Warriors looks NIIIIIICE. Don't think it's anymore "official" than Link's Crossbow Training or the CD-i games...but certainly looks like fun. Okay, maybe not like the CD-i games, then.
Mario Maker. Oh, man. I love homemade Mario levels like the insane "Asshole Mario" levels (search that on Youtube, seriously). Can't wait to see some insane Mario levels.
