Super Freak
I think it might be casue it has too much details, like wrinkles and veins popping out on the body. In the Videogame, you dont see any of those details so characters are more anime/cartoony look. ALso it looks like the Face is cut from another sculpt and just pasted on the bodyd. The level of detailing drops off significatly from body to face.
i think you hit the nail on the head there
