Wouldn't it be cool to find an ancient ship as an artifact , something with powerful unseen weaponry and unusual ship design... However this ship can be destroyed but it takes more than just a few ships to take it down , depending on the size of the ship artifact found. You may find an ancient alien cruiser or destroyer from some unknown race long since vanished..
I remember some old games in the past whereby a ship was found on a planet that either the technology could be used or the ship itself!
