I'm surprised that Knuckles gets a spot in Smash before Tails. (I mean they both can appear in the background of Green Hill, but that is different)

so we have (I think) 70 playable fighters so far, (8 costumes each) and 300+ possible stages (since each stage has two forms) with matches being anywhere from 2-8 fighters. That's 1,000,000's of possible fights,
