I've been hoping for a 3D 2D The Legend of Zelda (3D game, but using the vast and diverse overworlds of the 2D games) since forever, I hope the new Zelda finally delivers. Skyward Sword was such a disappointment in this respect...
The Captain Toad game looks awesome, Yoshi's Wooly Whatever looks cute as hell, Kirby's Stop-motion Canvas Curse looks hilariously ridiculous, Palutena and Mii for SSB4 were expected, I'm surprised X is actually a new Xenoblade (same universe?) and Mario Maker should be fun, I guess. There, I think I covered everything.
Can't wait for the Star Fox announcement in a bit (if the leaks/TIME article are correct) and the Smash invitational later today. My official prediction for the invitational is HugS, because he's neither the underdog nor someone the others will team up against in FFA, and I'm guessing the final match will mostly be decided by whoever happens to pick the least balanced character, which might as well be HugS. I hope DJNintendo wins, though, especially if he brings his Bowser plush.
Didn't really watch the other conferences, couldn't care less, whatever.
