I recommend joining our discussion on thread
https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=720570#Post720570 page #6 when it comes to trying to pin down what we actually want from BG2 to be in BG3.
If the IT'S DOS 3 argument even exists it's because DOS2 with only D&D 5th edition mechanics and lore would be enough if it was better. There are some features they simply put aside.
UI included. The fact there is at least 1 thing that was done in a clearer way in a game done 20 years ago then we have a problem after me.
A TONE of those features are hard to evaluate, preferences based. Most of us will bitch slap another for the " 6 party members" deemed useless by others. But if we can try to discuss it feature by feature in one place instead of having the same conversation with the same complaints over and over it would be a good thing. For us as players and for Larian as devs .
I have a lot of free time so I actually work on that list based on comments.
