Hey so since we have houses now and kitchen stove and stuff like that, what about cooking/crafting ?
for example you need gather resources like apples from trees or berries from bushes and then you can craft from it tasty yummy food that will gives you for example
Food that regenerates HP over time while running like 5 hp each 10 sec or something for duration of 60 -90 sec
Food that regenerates Chakra over time while running 5 chakra each 10 sec etc
And some similar food recipies like that, since we have houses cooking will add alot of RP gaming into Nin world
