Haha, I love this one!

It had that cheesy moment with the kid falling back, but yeah it's one of the better ones that Nintendo has done. I think that one along with these are Nintendo's best (in North America):

Super Smash Bros. (N64)

Super Mario Bros. 3 (NES)

I think that gameboy one with the middle-aged businessmen playing is the single most magical piece of marketing this side of the "Mean" Joe Green Coke ad.

      The   Smash Bros 64  commercial is a classic and  it would be cool if Nintendo would make a Smash Bros Wii U commercial similar  to it.

That is not only the best Nintendo commercial, but the best commercial ever.

Argh how did I forget that SMB3 commercial. That's the best one.

I have to say back then in the N64 era commercials used to be REALLY cheesy, but that's what made them epic! :D

Okay trailer..if you really look at it the only good thing was the music and the timing other wise in terms of commercials Nintendo sucks
