When I think of Geralt's upcoming appearance in Soul Calibur VI, I can't help but find it to be boring. Sure he's a perfect fit, his moves animate much like he does in Witcher 3, he's popular, he fits Soul Calibur's world tonally, and he's unique from the rest of the cast, but it was just too perfect of a decision that there was never a moment that I doubted he'd end up on the roster. It seems to me like it would be much more interesting if the crossover were done in reverse. I think Soul Calibur characters appearing in a Witcher game would be much more interesting of a cross-over than Geralt appearing in a Soul Calibur game.
Are there any cross-overs where you think it would have been better if it were the other way around?
