Games like X: Tension

X2: The Threat
A space sim with a story about Julian Gardna, but the real game is the universe itself: over 130 sectors to explore, 60 ships to fly, asteroids to mine and factories to build. Start with one small ship and a thin wallet, end up running a trading empire, or hunting the Khaak. It takes patience to learn, and it pays you back for years.
