 Endless Sky is a sandbox-style space exploration game similar to Elite,
 Escape Velocity, or Star Control.
 You start out as the captain of a tiny spaceship and can choose what to do
 from there.
 The game includes a major plot line and many minor missions, but you can
 choose whether you want to play through the plot or strike out on your own as
 a merchant or bounty hunter or explorer.
