You say that the game feels more like DOS than BG, which is another thing that has certainly been said before, though I do wonder if that's an initial impression that people naturally form due to the fact that the same engine has clearly been used as the basis of BG3, but that wears off over time as people get to know BG3 for itself. That might not be correct, but I have noticed that there seem to be fewer people mentioning DOS3 now, though that could be because they've got fed up saying it rather than because they no longer think it!
I still believe that, though I find it irrelevant to the quality of the game. I am fine with Larian doing their own thing, as long as what they do is coherent and of high quality.
