Meh I don't know. Sonic has always seemed to have the strangest fanbase in the existence of gaming fanbases because it appeals to the autistic and casual platformer gamers. I think the Sonic Team just struggles to come up with anything new and have it appeal to it's fanbase as they've been experimental with plenty of themes like Saturaday Morning cartoon style, classic style like Generations and Sonic Advance, and their level backgrounds and music are all very clever and different unlike what the Mario games have but still seem to have casino levels, undergrounds levels and lot of stuff in between. I think their trying to find the perfect audience still which should like a challenge and personally I think they should experiment less and stick to the basics of what makes the better games better.
