Here's my spiel, from a post which I posted without looking: The bags degrade like weapons, however, only the plastic and the tote bags do this, they degrade only when they have items inside them, and the degradation rate is calculated using the total amount that is inside them, their base stat, and whether you are walking, running, or creeping. When they break they drop all contents onto the ground. My next idea for that, also from the post I made without looking, is that these bags affect your walking speed. Say, you are carrying 20 items loosely, not in a bag, in your inventory, you would walk slower(in real life), right? so then , the player now receives a movement penalty based on all the loose items in their inventory, tote bags and plastic bags count, (unless equipped as secondary), whereas bags like the backpack and hiking bag (which can be much more easily slung over the shoulder) give no or little penalty. This would help reinforce good inventory management, and perhaps add a more (maybe optional) realistic feel to the game.
