At the other extreme I'm currently replaying Sacred 2 which is extremely silly. Even as someone who loves inappropriate humour I find it too much, but I figure if something's worth doing, it's worth going completely over the top!
I hated Sacred 2 for enormous amount of bugs and poor balance. Sacred 1 is way better in my opinion

Knowing Larian, we will get FOR SURE some amount of humour even in BG 3, but it will be much more toned comparing to D:OS 1 and 2.
I'm far more concerned about how they'll approach other aspects of the experience, like loot/itemization, progression system or the combat style.
I am with you mate. These features are most important.
