About the story you really need not say much because it is virtually non-existent.
Who knows Mario title that interested even not at all. Especially horny I find that you can re-select level previously. This means that you can turn on the console sometimes for 10 minutes to play simple 2 level. Something is perfect for traveling. Mario 64 or Galaxy were also absolute top titles, but a little more complicated on the go.
The only thing that has not bothered me a little, was the low level of difficulty. On the other hand I understand that as well, because such games can play younger generations should. I grew up with Mario and the SNES, and that should also be made to the kiddies of today possible. Therefore, you have to stop turning down a bit also the degree of difficulty.
I find the game incredibly well and am pleased with this purchase. Next week still comes Mario Kart added - I am happy! :)
Way to go, Nintendo!
