Do you think that pre rendered cutscenes help a game, or do you think that in-engine cutscenes are just as good or even better? I personally think that in-engine cutscnes are better, because pre rendered cutscnes are always gonna be the ones used in trailers, and you will be disappointed when you find out the game doesn't look that good.
Another reason I think in-engine cutscenes are better is because they don't really switch any graphics. I remember watching a Metal Gear Rising: Revengeance video where a guy uses the Grey Fox skin to defeat Senator Amrstrong, and the video had two very different costumes. The first was Raiden's regular costume, and the other the Grey Fox skin. This being a Metal Gear game, the cutscene was around half the length of the video. I actually forgot that Raide was supposed to be wearing Grey Fox's armor for a while. This made the video a bit disorienting, because I constantly had to remember Raiden wasn't supposed to be wearing his regular suit
