I think they do now, but I also think they should do more. Like what if you could shoot someone down, but then do it in a way where they survive and you can snatch up their escape pod. Turn then in for even more cash!
This could also lead to rescue missions where you can disable a ships by knocking out their powerplant then have the hostage or prisoner escape from a pod and you can swoop in and grab them. Works either way really.
OH! And you could even add turning in ship parts to be repaired if you want to use them or store them or just sell them.
A+ idea!!
