Suggestions arround more food supply management would not work in BG3 in my opinion due to the map design.
There is way too much food in the game, I definitely agree. To the point that the system itself doesn't make sense at all...
But I'm not sure it should be something to manage all day long when you travel, when you short rest, when you long rest... It would require us to gather more crap items, to manage our inventories and I think it could lead to too many situations in which the player is stuck (or forced to walk to find food). Limitations through food work well in Solasta but because dungeons are linear and because you often have to get back to town...
Can you please GM tell me the consequences of not eating in Solasta ? I know that you're never stucked but I don't exactly remember what happen. Your last playthrough is more recent than mine
