sonic is more mature now then either....not more childish
Lets go back 10years....sonic bubble bath,pjs and everykind of children clothes, 5 diff kinds of sonic comics, a cartoon were all he talked about were chilly dogs, goal of games were to save little animals, has a fat little body.
now: Has slick body with long legs, his story has nothing to do with saving baby animals, his cartoon has guns and cool cars and stuff, he has a mature storyline ect.
You THINK sonic is more kiddish now because you have matured geez
anyway sonic isnt excusive, There coming out with a sonic game for N-gage which looks like a poorly done port of sonic 1
