Hull, Engines, Shields and Weapons are covered under the basic damage rules and we have some ideas for System Damage but what we haven't talked about is damaging ammunition stores.
They technically fall under the Weapon but if we're going to allow Mines to be hit should we allow ammunition? Does it explode when hit? Do mines explode when hit?
If you're using Damage Control, probably not. The whole point of Damage Control is to return systems to operation. And it's pretty darn hard to restore exploded things to operation.
But if you're playing with 'system hits' then probably either could blow up. Do they do extra damage to the ship when they explode?
Just more thoughts. That actually spawn more thoughts I need to codify and post later.
