The reason I do manage to push myself with CRPGs like DOS, or more recently, Pathfinder WotR, is that the challenging turn-based combat in the higher difficulties alone works as an incentive. I always have that problem with games that last more than 80-100 hours, and that's the reason for I never finished Fallout 4 or Skyrim either. That said, I appreciate that you couldn't finish it, I had trouble too because the game went on for too long it felt. Which is funny when you consider at the same time there is an equally large sequit of fans of mediocre studios like Piranha Bites and similar companies that have showed nothing but clunky and disappointing products for the last 15 years. You're not alone, and I know this site in particular has a large sequit of Larian-haters for some reason, especially since they got the BG IP.
