I'm posting this here as I hope to see what people think about it for tes 6, but my thoughts are mainly towards Starfield, and how the implementation might relate to TES6.
In Starfield, the difficulty is customisable to the extreme, everything from ammo having weight in your inventory, to combat damage, to vendor credits. In my opinion, this makes it impossible for a consistent experience across players which means a lot of the time when a player is looking for advice on how to beat a challenging circumstance, the advice online usually boils down to "reduce the difficulty" in one way or another. Now Starfield didn't release with these settings availible, but I can't rule out that Bethesda aren't planning to have them available from the start for TES6.
How do you balance an economy for player A who wants to be able to sell the entire contents of one dungeon to one merchant and have enough money to buy anything they want, and player B who wants to grind quest rewards to buy an expensive item? If you design the game to have high value items available in stores, then your benefiting player Bs experience, while simultaneously giving player A too much power too easily, cheapening their experience.
I feel that introducing these settings makes the game a little too sandboxy for my liking and potentially leaves the community split based on approach
