Nintendo's showing definitely left a lot to be desired. With that being said, I was very impressed with how Mario Maker is shaping up and it's easily one of most anticipated games of the Fall right now. Aside from that, Xenoblade, and some cool trailers for games that aren't coming out for sometime; the Nintendo Digital Event was lackluster.
Like everyone else the new Metroid Prime is not what I want, but I will give it a chance when it releases. I just really hope the series returns to it's former glory soon. As someone who loves the series enough to get an 8-bit Metroid tattooed on them, I really want to see Samus make an epic return to form similar to when Metroid Prime released alongside Metroid Fusion and revitalized the series. Ever sense then it's been in a steep decline with Prime 3 being the last true game worth playing (I didn't care much for Prime 3 either because motion controls) Other-M was severe let-down.
