I disagree with this. Unless you rush it the game is longer and bigger than tyranny, I'm 100h into the game and I'm still far from the end it seems. I couldn't get far into pathfinder video games because they're meat grinders with shitty balance. For kingmaker I was so bored of fighting the same ethereal enemies over and over and over and fights were very tedious because I didn't have an optimized team.

Bg3 is open, both like open world and open scenario. Combat is as good as exploration or narration imo.

Now I love planescape torment direly. But BG3 is bigger than that imo. There are so many secrets everywhere, and so many branches. PST doesn't have so many pathes, it's more linear in some ways. The intensity of the scenario is comparable between the 2, but PST is deeper in the philosophy and more intimate.
