At what point will people admit they just don't want to play 5e? Lol.
I don't like kingmaker for a long list of reasons, but in the context of just resting I think it will never work for bg3. The whole purpose for it was to enforce the passage of time. You can't do that without a day and night cycle. Not to mention time limits, storage capacity limits, and introducing a cooking meal system. Might as well straight copy paste pathfinder systems and drop 5e.
My point is taking singular parts from a system is more complex than people make it seem. At a point it is not 5e anymore and at the same time some people are harassing the devs to make bg3 MORE like 5e. Lmao.
I mean you are free to do whatever you want. I just wanted to point that out.
There are a lot of issues I have with the game that making it more like 5e would fix. I really am enjoying Solasta which also uses supplies as a way to limit long rests and overall is way more loyal to the 5e system. And I actually like it more than BG3 for that reason among others. I just can't figure out a better way to handle long and short rests at this point, because the system for resting that they currently have just doesn't work and definitely needs to be changed.
