Heroes wouldn't have happened since it was made due to Iizuka wanting to go a different direction after multiplatform became an option, so we may have gotten different console games; the handheld games were mostly made independently up until 2010, so there wouldn't have been too many changes there...
Sonic X 2nd series/3rd season probably would've been an adaptation of World Adventure.

Werehog wasn't in the original design doc and Shadow wasn't supposed to return so soon.
