I hope to see more animated, or "exaggerated" poses for the characters, rather than just seeing them standing dead still for a half hour. ( when's the last time someone did that in a sonic game? ) over all, I think that this has great potential, with a very suspicious main character, and good use of side characters from the main series.
the one thing I think would be really cool though, is if instead of a standard turn based battle, reuse the sonic battle format. thats all from me, I can't wait to see more!
