Decent quiz, but some of the questions are shit.
I hate to sound like a total faggot/Sonic fan overload, but honestly you have to admit some of those questions had little to do with the actual franchise and were based on opinions not everyone has. (i.e. "When did the first crappy sonic game come out?" , "Who is the simple character?", and "Who made a comeback in sonic games?") Also with the chaos powers, there are an infinitely many amount, there is actually not a set number. As for Yuji Naka, he is the Programmer, not the producer. On one last note, Tails' IQ was never told. Only Eggman has the confirmed IQ of 300.
The quiz it's self was actually very good, but pretty generic in everything put presentation. Another disappointment is the fact there was no reward for the quiz such as a video, game, or even a cool picture to look at in triumph. As I said before, pretty generic, but there is a real potential I see. Good luck with your next flash!
