Kid Icarus: Uprising is so. Awesome!
If that's not elaborate enough for you, I just beat the story mode after a marathon that consumed my evening. And my 3DS battery. I spent several hours on my couch with my 3DS set into my Circle Pad Pro while also remaining directly plugged into the wall. I just couldn't put the game down. People can complain about the controls all they want, but I never had a single problem with them. I don't know what people are complaining about.
And the story is just wonderful. It starts off as a sort of revisiting of the original game with plenty of goofy poking at the NES days, but the writing and general sense of whimsy about the whole affair is so well written and voiced that when the game does get more serious, the characters remain endearing. Part of the reason I couldn't put the game down tonight was just to see the story through to the end. I couldn't go to bed leaving things unresolved. And yes, the story is a fairly simple one, all things considered, but damn if it doesn't have a lot of heart behind it.
I could write more in depth, but, well, spoilers. Also, I need to hit the sack soon. I'll try to write something more in depth tomorrow if I have time, but I will say this.
If you have a 3DS, play this game. Seriously. Just do it.
