ATLANTIS
A legend began when Plato first wrote and told the story. The legend is in Enduring, it endured through the Dark Ages, the Middle Ages, until it reached today. However, the actual empire of Atlantis is only hinted at today. The Atlantis I'm proposing is not Fantasy -- if you wanted fantasy Atlantis, that's someone else's game, not mine. It's science fiction.
PROPOSAL
After forty years of research into the legend of Atlantis, I propose the following scenario:
it's 700 AM (Al Mundis), seven hundred years from the time that Adam and Eve left the Garden of Eden. The place, an island in the Atlantic. (it's on Google Earth). The island is thriving civilization that surpasses ours on many levels. They generated power from the æther. They had computers, automobiles, and other mechanized machines. They had available all sorts of food stuffs. According to Plato, they had horse races and used elephants as beasts of burden. They have lights that don't burn out.
It's a science fiction Universe, Mankind has tinkered with genetics. His own as well as that of foodstuffs. Besides that, they mine Orichalcum (zinc) from the mountains.
I'm an Atlanteologist. And this is my Atlantis.
What you need:
* BESM d20 (Guardians of Order). BESM d20 is the only game that can do this type of science fiction well. Pathfinder is for fantasy. Starfinder could do it, but it's limited as to what it can do.
* d20 Mecha (Guardians of Order). This game features Mecha, of all things. While Starfinder has rules for Mecha, d20 Mecha does it better.
* GURPS Classic Atlantis (Steve Jackson Games). Although we aren't using any of the campaign models exactly, this book gets you started with the legend.
Oh, in case you want to train a cute monster (as a Pet Monster Trainer), you might need a copy of the BESM d20 Monster Manual, so you can have a cute pet monster to train. But it's not needed.
