In Star Control: Origins planets now sometimes have unidentified objects and structures for your landing parties to discover.
The orbital scan shows there is something, but the lander actually has to drive up to it.
You can often scavenge resources from the ruins of fallen civilizations or you can find crashed ships. Some you search, many you repair and add to your fleet.
Some of those ships actually are great. Many are not.
The Xontar Traveller is not a great ship. But it is a ship you find in great quantities. I think half of humanity's fleet is now Xontar Travellers. We could probably pretend humanity doesn't exist and we are in fact Xontar.
Or Xontar is a person who tries to impress women by crashing a ship on every known system.
No idea.
But I have 22 of those ships now in the hangar and am certain I will find more.
