Birth of the Empires

Because BotE is open source and the developers have kindly shared how to mod the files, it not only can improve, it can change with new major and minor extraterestrials. Thus they can all have their own technology, ships, troops, and buildings as well as their morality which are the will of the people.

The map can only accommodate 6 major aliens and 150 minor aliens so that colonization can grow. But these six empires can endlessly change with modders. Many major aliens can be added and the players select six.

You could have a historical period far flung in the future as these major species change their outlooks based on less or more hardship and so have different motivations.

Any amateur writer could create six new major races and 150 new minor aliens too.

If we could ever create a map, then established diplomatic relations might exist and so you would begin with friends, enemies, and those indifferent to your success or failure.
