IMO Don’t try to make a sequel, just make another story in the world. Call it Baldur’s Gate: GameTitleGoesHere

I’d take IWD though, I loved those games and own physical box copies I picked up at compUSA, and i’d even take it as a combat heavy spinoff with light story, just like the first one. Getting bogged down with dialogue in every city is a turnoff for me as much as I adore BG2/3. Was so nice bringing my own party and exploring the world, one dead beetle, lizardman or undead at a time.
