Starship Tycoon

Starship Tycoon is a sci-fi management/strategy game that puts you in charge of your own galactic shipping corporation.

You build your starships from scratch out of a wide range of different modules, choosing to be a cargo ship, a passenger carrier, maybe a smuggler or a carrier of hazardous cargo. You also choose who to employ as crew, or maybe to replace them with robots, and pick your own routes between different worlds. Starship Tycoon has a freeform 'sandbox' mode as well as a story-based 'mission' mode and also comes with a random map generator. As well as keep passengers and crew happy you will need to keep your ship repaired and in top condition, and keep on the right side of the customs officials and galactic police.
