Solar systems are big and complicated things; everyone seems to agree on that, though it's strategy maestros Arcen Games who actually went on and simulated a pretty whimsical and alien-populated one in order to let you rule it. Or at least try to rule it with the rather excellent The Last Federation.

It's a grand strategy game that has been wisely combined with tactical turn-based battles between eight different species and a very smart difficulty selection system. Also a game in which you can always ignore your warmongry side and sit back and enjoy a detailed simulation via the novel Observer mode.

The Last Federation is available for Windows, Mac OS and Linux via Steam, GOG and the Humble Store. For the next few days you'll be able to grab it with a 25% off discount too.
