I mean, the ‘hate’ has generally been described as ‘mediocre’, which even this particular modder said to explain his thoughts in a Reddit thread.
It’s good you enjoy it, but people can have different opinions. I agree with the opinion it’s mediocre, it feels vastly worse than Skyrim or Fallout 4 to me. I don’t think it’s impossible or even hard to fix into a good game, but I’m not awarding points for ‘could easily be better’.
