Nothing could have saved the Mercury Steam games. Bad idea from start to finish. As far as redesigns go, though, I'm having a hard time reconciling the classic "barbarian" image of Trevor and Simon. Leon was a knight, and yet somehow his descendants were barbarians? Just doesn't sit well with me.
If we got a reboot, I'd like to see the Belmonts as knights in general, with equipment upgrades that show on their costumes as they're obtained. Hell, let them use swords and other weapons aside from a whip, while you're at it. The whole thing about Leon abandoning everything, "even [his] sword", at the beginning of LoI was just laughable.
