Seed-World

Seed-Worlds are evogames where life is seeded onto a planet and is allowed to evolve from there. It's usually earth life that used to seed a world. These are different from ||Altenate Earths|| as those often still have other life from the time there, though many seed worlds have a very earth-like planet just for simplicity's sake. They're also different from ||Alien Planets|| as seed-worlds take a pre-established organism.
