I have an idea where you have a planet, and you can create bots that look like animals, and event them to make them progress in life, like for an example: You have a multaid at a scale of 0.500. He can grow 0.020 every 5 min while doing other things like farming, then after awhile, he could switch jobs like delivering the goods he farmed. Then he will eventually die and other multaids will have a funeral or something. Imagine that with+other multaids doing other stuff. They could progress a city and prosper, have wars, and have an ongoing race where players enter the game and start other Animal Races on other planets who will evolve and prosper. One nation could take over the next, and eventually, one will be on top, then you reset the server.
