Why not do long rests like they do in Solasta???
This would be very interresting... Especially because resting is not just a click on a button. It's a gameplay mechanics during which players have choices to make and things to do, exactly like in D&D... (hit dice, features, spells, level up,...).
Unfortunately Larian decided that long rest were a part of the story instead of a gameplay mechanic. Short rests are also very dissapointing at the moment...
