Running low on things like torches while underground or in a night fight could be a dramatic scenario
Please track encumbrance. I'm not worried about the little stuff but I dont want it abused, so at least add up armor and weapons and other major gear.
Also, please track the total gp value of your equipment, this is not so important right now, but later I will be able to gauge the party equipment balance and determine the starting wealth for characters beginning play later in the campaign.
I will track rations or pass that task off to a party member 'quartermater' who would also be the official keeper of the party loot.
