So, i'm thinking about this:
1. Food: NOT a ITEM. Can't be stored in inventory, can't be dropped on the ground, can't be grinded in masses by alts. Must be bought from food vendor.
2. How does it work: Buy it from food vendor. You fuck up at food vendor' faction, you won't get food.
3. Consequences: you have to follow the rules of the faction. (can't kill or steal faction members)
4. Prerequisites: food shouldn't be a nuisance, requiring a steak and waterbag every two minutes, but every game week. You always can afford a bite, if you not fuck up the reputation in current city. You can't die from malnutrition while offline. To get full character performance, you need to eat and you mustn't grind two hours for it.
That's it. Who was talking about grind?
