There’s obvious similarities with DOS games, but most of the DOS feel I get seems to be engine related stuff- how the camera control works, how you move characters, etc. plus some UI elements like container icons being the same, which hardly seems important but I guess could changed. It’s like DOS games about as much as all infinity engine (or similar) games are the same.

The characters, tone, art style, etc are very different, as is the combat system, the lack of equipment levelling, inclusion of skill checks. The lifelike character models, dialogue animations and cutscenes also go a long way to change the feel of it.

There’s a few more things they could do to differentiate the franchises. I agree with many others that the use of elemental surfaces could be toned down for example, and that’s the kind of thing they may well change based on feedback.

It was always going to be very different to BG 1 & 2 of course. Sticking to the formula of a 20 year old game wouldn’t have been very ambitious and IMO would have been doing it a disservice.
