I think it's about time we got an entry about Mario Kart. It's the biggest sub-series of Mario and Mario Kart Wii sold over 35 millions copies, making it the one of the best selling games of all time. It has spawned off memes like the infamous Spiny/Blue shell and (what I call) Baby X/ Metal X which is about putting baby, metal or another thing in front of the name of a character in order to create a new character (Inspired by Baby Daisy, Baby Rosalina, Metal Mario and Pink Gold Peach). This is actually quite popular on boards like GameFAQs.
So what do you say?
