What's more, imagine what would happen is Kamiya, after his successes, was finally given free reign of whatever he wanted of old Sega franchises.
Can you imagine stuff like Streets of Rage or old AM2 titles being re-legitimized as good games by Platinum, with free reign on whatever twists and turns he wants to give to the gameplay, title and presentation?
A Bare Knuckle/Streets of Rage sequel would be heavenly to see. But the thing is, you may not really need Kamiya's touch to do that much. Hashimoto (game design director for the likes of DMC, RE4, God Hand as well as Bayonetta) could likely do such a thing by himself, if necessary.
The Sonic fans will still complain.
As I've said before: I have no doubt in my mind that P* could probably make the best damn Sonic game ever made, if they really wanted to. But I still say it's not worth their time and effort. Plenty of other games in Sega's back-log could use P*'s attention, like the aforementioned SoR, Shinobi, Fighting Vipers, Comix Zone, Dynamite Deka (aka "Die Hard Arcade"), Golden Axe (a certain other game bearing the moniker does NOT EXIST, in my eyes!
), Virtual ON, JSR and more. Any one of these games getting the P* treatment would likely result in an "And the Fandom Rejoiced" moment, because these are largely maligned franchises that Sega either can't or won't do anything with otherwise.
Sonic, on the other hand, is smack dab in the middle of a clusterfuck that's basically due to nothing more than what Sega has allowed themselves. So no, I want Inaba and his crew to stay the [tornado fang] away from all that.
