Hello,
Since spacebattles usually leave a loser at the scene in pieces, why not use that to create a sight for research/exploration.
Sometimes it yields great amounts of debris sometimes nothing usefull.
You can use the debris for resources (reuse metals/components)
You can use the debris for research (analyze the debris, get research advancement points etcetera)
You can use it for politics (some races see it as an violation of a space grave, so secrecy is needed, or even leaving it untouched or protect it if its allied).
Just an idea.
Kind regards,
JacWar
