Pretty Good! =)
That was pretty good! The only problem I saw in this really was that to get the question about his age right, you had to choose 'sixteen'. Sonic is actually fifteen. ^__^;; I know in the oldschool games and whatnot he was sixteen (Sonic 3, for instance) but for SA, SA2 and Sonic Heroes, he's fifteen. I think they're sticking with that.
Anyhow, nifty quiz. You did a good job with the multiple choice thing. You made it so that usually the other options provided seemed possible, and didn't make it blatantly obvious which was the correct answer. The little pictures accompanying the questions suited well, and the Emerald Coast music was nice and calm. Good job ^^
