In case you were at all curious how you might play Mario Hoops 3-on-3 on the DS, there's an absolutely pitiful Japanese ad on YouTube that will show you. Apparently, there will be a lot of tapping going on. The one thing we may be even more curious about is why Nintendo still insists on using grown men dressed up as Mario and Luigi to peddle their wares. You know, Nintendo, that style is sooooo 1988.[Via Digg]
