Having played both Space RPG games, Star Nomad Elite is the closest gameplay-wise that I could find to fill that void.
It's a shame what happened with Space RPG. The developer used assets from a different game without permission and the whole situation got messy. There's threads about it here if you do some digging.
Try Star Nomad, it's a spacesim/trader/combat/etc.
Spacesims? Try Star Nomad.
