Yeah, I just
wrote about it on my blog on the most wanted characters I think most of us would like to have. Sonia, Manic, and I think even some of the SatAM cast should be able to be re-created. Sonichu will definitely have a few versions available made by fans, I hope the create a character mode is quite extensive.
Not only that but I'd also like to see people do Ken Penders' original characters
they should be rather easy to do as well as the Archie ones. And yes I think I will even end up making sdp the hedgehog
