Level scaling or challenge scaling or enemy scaling, whatever you wanna call it. The one that Oblivion was hated for, basically.
If you don't know yet what I'm talking about, I'm talking about the enemies automatically adjusting their strength to your own strength.
So will BG3 have it?
Skyrim is a great game, but of all the RPGs I've played, it's really only my third favorite. A huge part of why it's not number one is it's level scaling. I like RPGs where you get rewarded for putting in the effort to level up.
