I feel like my opinions might be of the minority, but I think Nintendo had a pretty decent showing. I'm REALLY pumped for Mario 3D World. I know that the game has been divisive, but I for one thought that 3D Land was one of the best Mario games I've played since the Galaxy games so I'm really looking forward to playing it more on Wii U. Donkey Kong looks fun, though I am disappointed we didn't see something else from Retro. I felt they played it a bit too safe, but a good game's a good game. I'll play it.
Bayonetta 2 looks pretty awesome (im a fan of the new hair do) and X still looks amazing to me. Mario Kart looks fun. And Smash Bros was a given for me since day -30 so you can imagine my jovial reaction to both Wii U and 3DS versions, as well as the inclusion of Mega Man.
Overall, they have some great stuff to look forward to, but the problem with them was the lack of surprise. Every game they showed, we knew about already. They played it really safe, and while it works to a degree, they could have taken some risk and showed something, idk, NEW. A new IP would have been nice to see from Retro, but whatever. DK is coming out this year, meaning they can move on sooner than later. Plus, they didn't show off any of the limbo franchises (Star Fox, and FZero) and no new Metroid makes me sad. I mean, i would have settled for a 2D one!
The thing that really bothered me though, was that my friends, who don't own Wii U's, were not very impressed by the showing and had no motive to go ahead and buy the system. They do plan on getting it closer to the launch of Smash, but right now, the PS4 is high on their radar because of the surpise and incentives that came along with their showings. And the 3rd parties are jumping ship like crazy, with Deus Ex: HR Directors Cut no longer exclusive either. Its a shame. I like my Wii U, and I'll probably buy a lot of the games they showed today, but its gonna have a tough time this holiday. I mean, cmon - PS4 is only 50 bucks cheaper! lol
Anyway, I'm still pleased for the most part. Hoping Nintendo will have more news to share in the coming months.
