I never played BG2, but I have played BG1, and I hate it with a passion. I hate clunky controls, where you can't have a thief check for traps and sneak at the same time, I hate Tarnesh at the Friendly Arm's Inn, I hate the chess level in Durlag's Tower, I hate random encounters with web traps that just turn your entire group off for about 5 mins of irl time. I didn't use any guides for the game, and learned to deal with every challenge with minimal losses, but it didn't feel like a victory. It felt like learning to live with a serious case of hemorrhoids. I also am not fond of the fact that nobody cares about your race/class, and the awful, juvenile dialogue with about 5 instances in the entire game where your choice affects the outcome (yes, that includes the Marl dialogue).
I'm no stranger to games that don't hold your hand much. I'm a huge fan of Morrowind, VtMB, both KotORs and many other old titles. When I play them, I feel that these games genuinely want to pull me into their atmosphere and provide reasonable chanllenge. And when I play BG1, it feels like the game wants to fuck with me just for the sake of it. To make the journey as bland, tedious and harrowing as possible. I hope to God that BG3 is nothing like at least one of it's predecessors.
Baldur's Gate 3 would be fortunate to run its tongue along the underside of
Baldur's Gate's boots.
