The BBC Micro version of this game sold 600,000 copies.
NES (Nintendo Entertainment System) developed a successful version in 1991.
It's considered one of the most influential and important videogames in the evolution of 3D graphics in later years.
Although the game features 256 planets in 8 different galaxies, none of them can be visited since it's a spaceship game, only being able to visit the dock station in each planet's orbit. An ID file was created specifically by each one of the 2044 different planets to explain economy, government, tech level, turnover, radius, population, dominant race and a short depiction about the own planet.
The game establishes eight different kinds of planetary government (in ascending order): anarchy, feudal, multi-government, dictatorship, communist, confederacy, democracy and corporate state.
