After replaying DOS1 and 2, i noticed few similarities both games had that i disliked.
Such as:
Both games were somewhat linear in nature. Map seemingly being divided in leveled areas where you had to proceed in certain order or be obliterated by enemies (or is this simply"git gud" moment i failed?). A single level up seemingly making all the difference in the encounter difficulty. Hopefully this is avoided with DnD rules in place.
Quest lines seemingly leading nowhere. Like the comatose little girl that could be found in the tomb. Before the definitive edition she simply disappeared after 3rd(?) act. I think there was a mage in the first game, after killing 4 totem demons, that lead nowhere. Or just are underwhelming: Anathema.
Some plot holes/choices not mattering. Mostly from DOS2, i chose to vampirise the souls of main villains that i killed. I was under assumptions that they were obliterated during that, but no ,final boss summons them anyway.
Difficulty spike during last act. This was a huge problem for me. After i got to last act of DOS2, before the fight where difficult, but manageable, Then i had my ass handed by everyone.
Poor endgame sequences. From having to babysit NPC in first game to being obliterated without even getting a turn when faze 2 started in the second. I consider both to be somewhat poor bossfights.
These are my gripes that i hope are avoided in Baldur's gate development.
Also i wanted to know what do kind of thing you dont want to see when the game is complete?
