Sandbox-style space exploration game similar to Elite, Escape Velocity, or Star Control

<rendered-html><p>Endless Sky is a sandbox-style space exploration game. You start 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 play as a merchant, bounty hunter, or explorer entirely at your own discretion. Trade goods between star systems, upgrade your ship, recruit a fleet, and uncover alien civilisations beyond the boundaries of human space.</p> </rendered-html>
