I think one of the reasons that the AI feels so robotic (well besides the actual AI) is that most of the character animations are so emotionless
Like yea there's a few ones that's filled with emotions specifically, like when they shout after you leave the house, but what i'm talking about mostly is the locomotion movement animations. They dont even have facial animations which makes the character just look robotic
I think Mr. Peterson suffers from this issue most (even though the other characters have this issue too). When he's chasing you he just looks blank, He should be like be angry, or get annoyed when seeing you after a hundred times. Or get more angry in the getting hit animation. In his Idle he should look around and think about his life or something. Not just look at you emotionless
I think revamping the ingame animations for the characters with more emotions would improve the game so much. I added some examples with Mr. Peterson where i think this issue is the most apparent
