This is a simulation of interstellar colonization, similar to the game Seedship. The user controls a colony ship that travels at relativistic speeds, and has to weigh the integrity of the ship vs whether to settle a planet. Planets are randomly generated but always interesting and always present trade offs. Prioritize unique planets, for example on in the habitable zone of a white dwarf, one that’s a temperate gas giant, one that orbits at a lagrange point, etc. Be imaginative but still using plausible science. When arriving at a new candidate planet, the user is prompted to launch scanning probes or just do an orbital survey, which gives info on resources, characteristics, etc.
