An interesting self-imposed challenge to go with those who do things like play with only 1 bar of power in Engines (or even disable engines in battle) or play with no shields.
Up until life support is destroyed and you slowly suffocate because the store is in an inconvenient location
Perhaps it could be extended to those events where they offer to repair your hull. Get hull repairs from an event? Feel free to repair your ship now.
If it were the engines, the ship would pretty much be floating.
How about "Emergency repairs?"
If a system gets damaged, you can fix it to Level 1 (or 2 in case of Shields) but no higher until you go to a store for proper repairs or if someone fixes up your hull.
That also solves the Life Support issue - until you hit a Slug who disables your oxygen and your Life support is at level 2 but damaged
And obviously you would have to be allowed to fix the helm.
And it would discourage you from upgrading the helm to level 2-3 (not that it was already discouraged) because if your helm is damaged "emergency repairs" would dictate you can only restore it to level 1 and you have to move the pilot out.
Would the challenge be negated by a System Repair Drone or you just don't use them in the first place?
System repair drones (and hull repair drones?) are really interesting when it comes to the use in this type of gameplay. Im not sure what i would do with them in such a case, as I haven't experimented with them yet.
Idea:
Repair drones can fix an entire system but only 1 system per jump. So let's say your shields and doors are damaged, it can then fix the shields up, then you power down the drone and next jump, you power it up and have it repair the next system. If the drone is destroyed in the process, you can fix another system when you make a new one.
Hull Repair Drones? How many bars of damage it fixes is how many you can repair.
You have 6 drone parts, your repair drone is already out and you absolutely need to fix more than one bar. So you do it, and continue your game as if you had one less drone part. So when your counter reaches one, or whatever number you's managed to tally up, you're "officially" out of drones.
