i understand why you are disappointed you dont regenerate shp or stamina, but i would also like your analysis on how this would affect the game.
In my opinion, it doesnt add anything, except that people will log out instead of need to gather food to regenerate shp, and they dont actually have to actively play for it to take place.
People would log out more often, especially if they think they are vulnerable, unless you want to make them starve while sleeping.
I truly see no actual benefit, except for people to see happen what they expect to happen, for no other reason than other games do the same
