I’m rather fond of space games, and I like the idea of Navigation as the theme. Imagine your sailing craft in space, solar sails trimmed to align with the solar plane, you’re awake to check your position in space, make adjustments, hoping to align your craft for a gravity corridor opening up between Jupiter and Saturn. All you have is the sun at your back, a telescope and the stars in the sky around you.

• Find and chart the position of the planets
• if your target is a moon, find or calculate the moons position
• figure out where you are in space by triangulating
• work out your speed by comparing to previous measurements
• tweak the sails, or burn precious fuel to make a course adjustment
• hibernate for days or months

if you miscalculated, or you put the sails in the wrong position your could be hundreds of thousands of miles from where you expected to be.

But get it right, and you’ll fly by the most beautiful planets, moons, stars, or trail along side comets as they sparkle in the light of the sun, or run silent in the shade of deep space

Just writing that gets me excited for a crazy like that!
