I can't say i'm excited about this game. I think, like quite a bit of people, I didn't really ask for not wanted an new IP. What I love about Nintendo hardware, and the main reason why I buy them, is that it gets me the classic Nintendo games I've always liked.
Sure, sure, this might be great and we should never ever shun a new IP just because it's "different" or unexpected. I'm all behind that and props to them for going in the fray with something new...
...except there isn't a fray (let's not pretend for a second that they've got competition here), and there are some fan-loved IPs that have been too long gone. Advance wars, Metroid, F-Zero have all been cited in the pre-reveal thread for good reasons, along with Mother. I mean, it's great to have something brand new, but why can't we have both a brand new IP and a new game from a license fans are longing to get back into?
Nintendo's Wii U reveals were much better in that aspect. You get the squid game with a name I can't remember (ever), yay !, but you also get Yoshi's Wooly World, yay too! That's what I'd have liked to see for the 3DS this E3. I'm spoiled as fuck.
