(Spoiler alert)
Removing one of the main characters from the previous game and forcing you to play as their killer is just stupid. People play single player games for the story and forcing you to not only sympathize with, but play a solid portion of the game as the killer of someone you became attached to does not make sense regardless of the reasons or justifications. I feel like they were trying to do too much with the plot here. I would have totally been okay with them killing off characters but playing as the killer is just too much.
