Sounds like a fairly typical 1990s kids movie, the part with Robotnik recruiting bullies as his lackeys is reminiscent of things like the first Ninja Turtles. Probably best off that it never got made, I doubt the CGI of that era would have been anywhere near good enough. The interesting part is how it would've treated Sonic as an actual video game character coming into the real world. It's not a particularly original idea, and yet I can't think of a video game based movie that's actually taken this approach.
