We are beginning to enter the level of absurd numbers.
And that certainly won't help in the discussion.
You still don't understand something. You sound like the decision to take a short break or go back to the trader is complicated.
Mercy, the game has a dense network of fast travel, which means that we can come back to the trader at any time.
And you will definitely come back even more often after picking up anything that is not nailed to the ground.
I assume the traders will always have enough supplies to allow the player to rest otherwise the player could be blocked. Rather, every trader should have that much because you have one regular trader who doesn't leave or get murdered by us (or even not).
If they introduced a time limit or an inventory reset, they would be eaten alive by players and reviewers, therefore it will not appear. Nobody will deliberately spoil the game's ratings.
Increasing the amount of food due to the number of people in the camp literally punishes the player for playing the game. While I can bear the cost on each companion, the additional characters shouldn't cost you anything.
Why the hell then keep useless characters like Volo in the camp? You can't even kick them without killing them.
In the full version we will have 8 companions (maybe even less because one has probably been replaced or removed), it is still only 2x more than at present.
Also what about multiplayer? Then what players are punished for playing together. 40 extra food for rest is a lot to start with if they want to experience the history of companions.
