So much arguing over the different Mario Kart games, sigh....the SNES original doesn't hold up well as being worthwhile against its successors, but that doesn't mean it belongs in a 'worst of SNES' thread....
Just to throw in though, I get my MK fix from the DS version. The controls handle well, there are a bunch of new tracks AND a 'retro circuit' with prior games' tracks remade, I'm pretty sure no other game had the amusing Blooper weapon, very decent graphics, multiple karts to choose for each character, you can easily unlock Dry Bones as a playable character, and with some effort I know there are a bunch of other extras...all this, and it supports up to EIGHT players! Hell yeah! There's even a 'download play' mode (non-DS owners, yes, the 'everyone needs a copy' problem from old linkable portable games has been fixed) that limits the available tracks and forces people without the cart to play as a Shyguy, but still good fun!
Besides, you can play it outside....or a diner....or if you show up too early for a movie and have to sit through the commercials-and-BS 'MovieWatcher Network' crap before the trailers...or waiting on the endless registration line at Otakon (okay, falls under outside)...blah blah blah blah.....
TL;DR- Mario Kart DS is pure win
