Mario Kart Specifically? It's mindless fun especially with friends! It's kind of like a MP Astro Bot of Racers! The graphics etc aren't great, but the smooothness, the the tracks and courses that can go up/down/indoors/outdoors/underwater and many more is brilliant in level design along with the maddening random power ups and ways for you to even trip up and block other people's races! The game takes you to the fun you had in childhood with video games! That's kind of the USP of all Nintendo games too! It's really hard to beat their creativity, level design and gameplay in most games! For Mario Kart - I don't think there's any major publisher doing similar game at all!
