I think this is a great idea!i was wondering if you could have a scale to this part,
that is; if all player characters were on larger ships, then fighters fights could be resolved at a more simplistic level,
but if characters were piloting fighters or other small craft a more detailed set of damage rules could be slotted into it for that situation.
in FT/EFSB you just rolled a die to determine number of fighters destroyed, in B5Wars you had to destroy several systems per fighter for a kill,... a relaible way of swithing between the two, depending on wether any characters were involved, might help the speed of play for the game.
A friend of mine used to run all NPC ships on a simple light/medium/heavy damage system (stolen from JB007) and PC ship on the charts from Renegade Legion: Interceptor - it worked very well with quick battle results but detailed effects on the PC ship.
Perhaps Mongoose can work on a dual system - simple for big battles or dealing quickly with NPC ships and something more detailed for the PCs.
(and please don't go for the PPGs just because I want to give you even more work! )
