Dimps has typically been in charge of the handheld Sonic the Hedgehog releases. I think if they'd been given developmental control over Sonic Unleashed, the game would have been much, much better. As anyone who played SU knows, the game had enormous potential, particularly the Daytime stages. With Dimps at the helm, it seems likely that the Nighttime stages would have been dropped altogether in favor of a focus on the better, less gimmicky half of the game.
Seems like I'm getting my wish at least partially, since Dimps is doing Sonic 4, but still, I can't help but wonder what it would have been like if they'd taken over sooner. The Daytime stages of SU honestly were the most fun I've had in a Sonic game in a long, long time. It would have been great to see a game based entirely around them.
