Needs a toggle function yes. If people like it, fine, but to me it makes the game look less realistic in the current form.
It only affects the group
People wouldn’t get that dirty by just running around
The game doesn’t provide a feeling that a long period of time passed otherwise, so it’s looks like our party just loves to put our faces in mud.
You’d at least wash your face, there is ample water everywhere
Everyone else is sparkly clean but doesn’t comment on your appearance
Please provide a toggle function so people can decide if they want to add it or not.
