Satoshi admits to picking the best characters of each game.
I really don't care what people play. I just pick characters I enjoy. Sometimes they're good... most the time they're horrible. It's not so much about winning as it is having a very exciting match. Weak characters and bad match ups always give me a boner for some reason.
Oh, and for what it's worth. I think you'll only be amazing when you commit to a character you truely like. That's why you get people like kuroda, rx, n-o, bleed, and other godlike sobs
