I mean. I don’t recall levels being displayed in the original games ? As you mentioned, there is already an easy to use save / load feature and there is also a ridiculously accessible short rest / long rest option. So far I don’t see a permanent death either, I guess unless you shove the gith off the ship ?

Lore should fill in the blanks for monsters that you’re unfamiliar with, but may encounter in a combat situation. Maybe your character uses one of his skills to roll against to consider the threat of an enemy - like history, lore, arcana, idk.

I don’t love seeing total hitpoints numerically either, though. These numbers - levels - hitpoints - whatever, it’s all going to be available in the game files and easily accessible on the internet anyway.

Playing without those numbers available to you means that you’re going to play differently, and that’s ok.
