Doesn't this run on the same engine as Witcher 3? I feel like the AI in it's general behavior is exactly the same as it was in Witcher 3 and thus I doubt they're going to change anything major about it. It indeed bugs out a bit more, so I think that'll need to be adressed in patches but I wouldn't expect them to make the npcs change their general behavior much.
In all honesty though, if it was good enough for Witcher 3 to still be a great game, I think this will be fine eventually as well. It just won't match the expectations of many.
I still think that the overall story and gameplay are promising though.
