One of the main features of Elite: Dangerous is traveling to and discovering new star systems in the Milky Way Galaxy. Spending ages scanning space bodies, gathering data, landing on planets – all of those make up ED's primary draw. The average commander can spend not only hours, but days and months travelling to the edges of the Galaxy and back -- all in the name of discovery.
Perhaps discovering an ancient world with Conan could give ED players the same level of excitement, or perhaps even more? There are dungeons there, vast lands to cross, ancient tribes to fight, and all sorts of creatures to discover.
Any explorer -- even one from space -- should be able to find something interesting in the Conan Exiles universe.
