When he runs though, he looks like he has on really tight pants, or else has to go to the bathroom... (adjusted in JA)
The difference between SP and MP in either game is dramatic. I prefer the MP animations though. Sure they're less flashy, but I feel like I'm more in control. That it's tighter and more controlled gives a good feedback, even if it's less showy. Maybe "more human" is right like you were saying, but for a game, I prefer consistency in some cases.
