It gains nothing from being gory and violent because I really doubt that would translate well into the low poly artsyle UII has so far. Your model, for example, is far too high poly compared to anything we have seen in UII. The “darker” people have been throwing around is an comparison to previous iterations of the game, not compared to other games. We dont want dead space, we want a game where the turned look fairly intimidating. Also, that much gore just doesn’t add anything to the game other than taboo, which little kids love, and you would probably see more little kids playing the game the more violent it is, which is kinda funny to think about. Also the game would probably have to do some legal age restriction stuff, which I know nothing about, but would probably be a hassel for nelson.
TL:DR gore adds nothing and is a lazy substitute for turned design.
