Alright so far I've involved keeping track of food and water which isn't so bad except for the fact my players are starting out with nothing except the clothes on their backs. Weather is gonna play a big factor at the start since it's the beginning of winter. They'll have to contest against npc's that want to live too. I've also decided to make little additions that are optional. The long and short of those is they add to the class and play style you have one in specific is the Archer. Making your own bows & arrows along with gaining advantages and little perks to it. What else can I do to add on to everything but not be too much to keep track of?
