Maybe it should only apply if they fired on police or GalCop stations in that system?
There would certainly be an argument in favour of making a system where the player became a fugitive more hostile … Oolite's legal ratings are incredibly low-resolution, and it wouldn't hurt to have a couple of extra degrees of criminality, e.g.
- Fugitive: Shoot on Sight (for becoming a fugitive by destroying another ship in that system)
- Fugitive: Most Wanted (for becoming a fugitive by attacking another ship in that system)
I think that anyone with any sort of Fugitive rating should be immediately arrested on docking in a main system station, and subjected to a LARGE fine (a significant percentage of the player's cash – 50% maybe?) and a time-penalty of several weeks at least. Fugitive: Most Wanted players who dock get a 75% fine, and Fugitive: Shoot on Sight players who dock get Game Over. Now that players can save the game outside of main system stations, I don't think this would be unreasonable.
Edited to add: Fugitive: Shoot on Sight and Fugitive: Most Wanted would be downgraded to basic Fugitive on jumping out.
