Meh, D:OS2 is a great game until the latter 1/4th in my opinion. Act 1/2 are fantastic, act 3 drags a bit and act 4(arx) is the absolute worst in my opinion. I sincerely hope BG3 doesn't have the same problem, since D:OS1 had a similar issue where it was great until the very end for me(scavenger hunt.) Sadly i dislike the latter parts of each game enough i'm just not inclined to ever replay them. It really soured the whole experience for me unfortunately.
Arguably the definitive edition makes D:OS2 worse too, since it makes side quests damn near mandatory or else you'll be constantly underleveled.
