I think thats an interesting trend for Nintendo, at least for this gen. They won't necessarily blow you away from the get go, but once you see more, you gain more interest. It made games like 3D World look much better than we realized.

The only games that I think blew people away from their first trailers were Pokemon XY, Smash Bros. for 3DS and Wii U, and Zelda U (though it was only a teaser at E3).

Is always the same, Nintendo reveals a new game with a trailer, everyone shits about it (specially about graphics, because gameplay is the most important amirite?) then some rational people say "wait before judge", no one cares because hating is more fun, and then when the game is about to be released Nintendo shows new trailers and suddlenly most of the people shitting about it now thinks it looks great. Is the same story, people never learn.

And yes, good trailer.

I'll admit I had my doubts when I first saw it, it didn't really look impressive, and I'd never played the original or whatever, wasn't planning on it either... but this trailer has swayed me, the graphics seem to look better than I recall the first time seeing it, and it genuinely looks interesting, so I reckon I'm gonna' pick it up

... Not straight away though, I've already got a HUGE backlog of games, and I'm trying my hardest not to make it bigger, there's still tons of games I've not bought yet, and this will come AFTER them, but I'll be picking it up at some point, I've heard a lot of good things about the game anyway.
