Let's see, Sonic Adventure, Sonic Adventure 2, Shadow the Hedgehog, and Sonic '06, that's 4 games where the cast of Sonic interacted with normal looking humans. It took Sonic Team something like 9 years to realize "You know what, our cartoony protagonists look kind of out of place next to these guys." and replace the human cast in Sonic Unleashed with much more cartoonish types that stylistically match Sonic and his friends a little better. I'm not complaining, its pretty funny but I like the cartoony look of the townspeople, but there is one little problem I have.

The entire population in all the cities are apparently human! I never see any other furry people except the new cast members that get introduced, yet the humans never react strangely, like "Holy crap! A talking hedgehog!" That means that mobians (That's the only name I know to call Sonic's "race" by) must be common enough that everyone has already seen them, but why do we never see anyone besides Sonic, his friends, and whatever new character is getting introduced? There were a couple dozen named human characters in this game, why couldn't they put in just a couple cartoon animals in? I'm ranting now.
