First off, about my data. Stop saying it doesn't prove anything. You can plainly see that it, at the very least, proves MK overcentralizes the game to the point where he is selected 1 in 5 times when we have a whole cast of 38 characters. To a lesser extent, MK's dominance shines through with the whole "money won/usage" ratio business. He has the highest, AKA MK receives the more money than any other character for being picked once.
Stop saying "lol this proves nothing" and giving arbitrary, useless explanations for why the data is as it is. It proves MK's enormous presence in the meta-game, beyond a shadow of a doubt.
Because it was still around for a few years and has comparable data. SF4 is a much simpler game as well, so there's not nearly as much of a learning phase as Brawl has had. It was pretty much that way since the start.
A game doesn't become mainstream because of simplicity... It's generally the latest game, and lo and behold, it was a balanced remake of the unbalanced game. Why would anyone cry about a character when they know they can just wait for a balance patch?
The starter list with 5 and 7 doesnt start MK on one of his worst stages, although it might in specific MUs. And everyone else has to deal with their opponents CP just like MK.
The starter list doesn't have Delfino, Frigate, RC, or Brinstar.
Just because MK still wins on starter stages doesn't mean they're not his worst stages.
