The creators of 'Elite' had this problem way back in the 1980's when they had to squeeze 8 galaxies complete with planet data into 32K of RAM. They solved the problem by 'procedurally generating' all of the required data from a seed number. Therefore, it isn't a question of cutting and pasting from Wikipedia etc., it is more a matter of getting the right 'seed number' for earth, updating the procedure for generating content and that should be it.<p>Anyway, here is something cut 'n' pasted from Wikipedia:<p><i>The Elite universe contains eight galaxies, each with 256 planets to explore. Due to the limited capabilities of 8-bit computers, these worlds are procedurally generated. A single seed number is run through a fixed algorithm the appropriate number of times and creates a sequence of numbers determining each planet's complete composition (position in the galaxy, prices of commodities, and even name and local details— text strings are chosen numerically from a lookup table and assembled to produce unique descriptions for each planet). This means that no extra memory is needed to store the characteristics of each planet, yet each is unique and has fixed properties. Each galaxy is also procedurally generated from the first.<p>However, the use of procedural generation created a few problems. There are a number of poorly located systems that can be reached only by galactic hyperspace— these are more than 7 light years from their nearest neighbour, thus trapping the traveller. Braben and Bell also checked that none of the system names were profane - removing an entire galaxy after finding a planet named "Arse".[9]</i><p>[9] Procedurally generated by unicorns.
