then you'd rather loose an entire fleet due to fuel shortage rather than spare the OP to have a ship to PREVENT that scenario ?
When did I say that it would be a good idea to send out an entire fleet on places where they would run out of fuel before they get to somewhere they can replenish? That and I was under the impression that your commentary on the book was based on real life space, not Starfarer space (which is still a bit odd since in Starfarer universe sub light travel is basically free as long as your ships can move).
In the finished game fuel WILL be needed to jump from sector to sector, hence if you didn't have a ship to produce fuel out of supplies and you run out you're pretty much f*cked.
That's assuming that there will be sectors that are completely void since fuel is suppose to only matter for sector to sector movement... and again, your comment looks like it's just talking about space travel in general, not Starfarer because of many things that requires context that simply doesn't exist in Starfarer.
For example, the function of refining raw materials into fuel doesn't even exist yet so such feature would have to added first before even thinking about refinery ships. Second, there is nothing more basic unit/type of resource than "supplies", so the idea of putting together "supplies" from scraps would mean implementing unit/type of resource that's even more basic.
All of which are fine idea, but that's a whole lot of assumptions to make that all of it would be implemented into the game. I would rather discuss each of these ideas on their own until something similar is implemented into the game.
