Game data used in the game is generally implemented as data sets in code that can be looked up on the order of nanoseconds as collection containers, game objects, or other arrays and pointers and whatnot. This data is held in main memory and directly accessed.

I understand what a horrible mistake I was going to make now.

Anyway, I've decided to use 'maps' in my game and not generating the solar system positions automatically. Instead, system names, number of planets/satellites, planet sizes and everything I use is stored in structures and picked automatically from those when I load the game scene. I'm looking forward to see how this method turns out.

Thanks everyone for helping me get this far.
