Sonic Generations with Ryan Drummond & the original voice cast
Sonic Generations redubbed cutscenes with Ryan Drummond as the voice of Sonic as he should've been. As well as the most of the characters keeping their original voices. I also substituted Generations' bland BGM with tracks from previous Sonic games. As for the cast:
Sonic the Hedgehog: Ryan Drummond
Miles "Tails" Prower: Corey Bringas and Connor Bringas
Amy Rose: Jennifer Douillard
Knuckles the Echidna: Scott Dreier and DAN GREEN
