Pokémon in Space
It’s essentially Pokémon meets Star Trek, but without as many deep, moral messages or social commentaries.
The idea is that the known world is composed of small systems of planets arranged in nonsensical ways that they all pretty much share the same atmosphere and aren’t separated by much more than a good jump between gravitational fields—Super Mario Galaxy systems, essentially. These systems are, for all intents and purposes, the equivalent of a town or city and its surrounding area. These systems are provinces under a federation (I think it’s a federation, right?) that makes up the whole of known space.
To keep the peace, Astronauts, the crews of the cruisers that patrol space, are employed and sent around. Their job entails law enforcement, rescue, and so on. The players would make up the designated ground team of a cruiser tasked to float around in the further reaches of space.
