I was wondering about this for a while, so me and a friend had this debate going on for a bit. I said that the Sonic characters do not need as much character development since the storyline is basically run-stop Eggman-stop another big baddie and the fact that it's just about a blue, anthropomorphic cartoon hedgehog and his friends. But then my friend says that with character development, the characters themselves can seem more interesting if their personalities were a bit...deep, as to say. Which I can agree with, but I couldn't help but think that maybe the fans wouldn't pay too much to that rather than just play for the gameplay itself.
So, what's your take on this? All opinions welcome, but don't let it get out of control.
