Okay, where to begin:
Firstly, I loved the Nintendo direct event, especially with the humour and developer interviews. Really hope they keep it up with this entertaining and informative presentations, things like that cannot be done at a conference.
Games:
Yoshi's Woolly World = Yoshi's Island + Kirby's Epic Yarn. Definitely not a bad looking game, though i hope it recieves a better reception then New Island.
Smash Bros = I'm more interested in this series then I was before, while admittedly not a big fan of fighting games. It's shaping up to be a good game, with lots of content, and I quite liked the inclusion of the Miis, albeit very predictable. I'm considering getting the game, maybe even both copies, though perhaps not at full price.
amiibo = Why does this feel so natural? Like, this seems much less of a cash grab then Infinity or Skylanders, as it will be used for multiple titles (admittedly all including Mario at the moment, dosen't really spread the love) The toys themselves look great as well. The natural fit for the Wii U's NFC slot, and I may buy a few myself, if the promised Smash Bros-levelling up is anything to go by.
Zelda U = Really not much to say. While the art style is gorgeous, I want to see some gameplay before I get to a judgement. The promise of an open world is there and good luck, but I want to see it in action, rather then just a landscape. Yes, I'm a bit skeptical although I hope for the best, but there's a lack of content to look over.
Splatoon = LIKE SERIOUSLY WHAT THE HELL IS THIS GAME. I first thought it was a Nicktoons game, but it's Nintendo trying their hands at a shooter. And I'm hoping this game is content-heavy, because this game looks original, unique and can hold it's own against the Call of Duty's of this world. It also reminds me of de Blob, not a bad thing. I really hope it sells well as I'm really looking forward to it - I'm going to place bets it'll be out in Spring 2015.
Captain Toads Treasure Trackers = Captain Toad: Full Game Edition. And a great-looking one at that. And the trailer was very well done, with gameplay a-plenty. I wonder how much gameplay there is with this game, because I'm hoping for many levels.
Mario Maker = SMBX>Mario Maker. Mario Maker gets consolation points because it's official.
Codename: S.T.E.A.M = Looking good, and bizarre, though I'm not too sure on the shooter-based gameplay. Still, I'm willing to give this a try

Fantasy Life = I was hoping for a Dragon Quest game, and still do, though I remember being excited for this one, and this game looks to be a long one. However, I want to wait out for one of the five Dragon Quest games to be released here, and buy this cheaper. Sorry, Fantasy Life.
Devil's Third = Way too much tattoos. And blood. But still, it's a Wii U exclusive.
Mario Party 10 = Bowser Chase 2k14. Really not much to say.
Mario Vs. Donkey Kong = Kinda looks like the last one in HD.
Bayonetta 2 = I'm more interested in this then I was. The gameplay looks fluid and fast-paced. And the original will be bundled in with it! Basically 2 games for 1, which is a bonus!! If you're certain you'll like it, which I'm not, so buying it discounted will be the route I'm taking if I choose to purchase it at all.
Kirby and the Rainbow Curse = Nothing to say apart from it looks good.
Star Fox U = Similar to Zelda U. Gameplay please. And perferably not waiting 3 or 4 years for release, thank you.
Project Guard/Project Giant Robot = Too ealry to come to any conclusions, but if these are the new IPs Miyamoto was talking about then time is the best thing for these games at the moment.
Xenoblade Chronicles X = Best name ever 10/10. Still, I am interested in this game, however.
Indie games = There's lots of them. I don't remember the trailer of the top of my head, but it's good to see so much support for the Wii U/3DS eShop.
Other Stuff:
Kingdom Hearts 2.5 = Disappointed about no Mirage Arena Online. The time ocnstraints excuse is bollocks. Still, I'm loving the HD visuals!

GTA V Next-Gen = Predictable.
Anything not said wasn't that remarkable or interesting in my opinion. Which is basically everything else.
