If you ever felt that exploring the solar system in the base game was a bit too 'brief', fuel up because Outer Planets is here to take you much further! This expansion is the essential upgrade for anyone looking to look beyond Earth's orbit and dive headfirst into the chaos and beauty of the gas giants. Now, your playground expands to include Jupiter, Saturn, Uranus, and Neptune, turning the board into a true interplanetary arena.

The exploration dynamics gain layers of complexity that you'll love (or struggle with, depending on your level of cosmic optimism). The real highlight here is the mission progression: you don't just travel to these new worlds; what you discover there—whether it's a rare resource or an unexpected phenomenon—can unlock new and even more challenging missions. It's a cycle of discovery that keeps the adrenaline pumping, as what you find on a moon of Jupiter might be the trigger for an epic journey toward Saturn's rings.

For those who have already mastered the original Leaving Earth, this expansion isn't just 'ore of the same.' It ramps up the simulation level, demanding even more precise route planning and much more strategic resource management. You'll have to deal with colossal distances and the logistics of delivering supplies to the far reaches of the solar system. If you're the type who loves a high-level challenge, with rules that simulate the reality of a space agency, this expansion is your next mandatory destination. Prepare your crew, calibrate your instruments, and get ready to explore the deepest parts of our solar system!
