Hi. I'm making a game like Civilizations and Humankind. Here are the ages in my game:
1. Stone Age (approx. 2.5 million BCE - 3000 BCE): In a world untouched by civilization, primitive tribes roam vast landscapes, thriving through their mastery of stone tools, fire, and the art of survival, living harmoniously with nature whilst slowly unraveling the secrets of the natural world.

5. Early Middle Age (approx. 476 CE - 900 CE): From the ashes of fallen empires, fragmented kingdoms rise, navigating the winding labyrinth of feudalism, where chivalrous knights and wise rulers shape their destinies, amidst dark ages and turbulent times, searching for stability and enlightenment.
6. High Middle Age (approx. 900 CE - 1300 CE): The resplendent era flourishes, adorned with soaring cathedrals and tales of valor, as feudalism gradually gives way to nascent cities, bustling with trade, invention, and a rekindled pursuit of knowledge, launching humanity towards a path of progress.
7. Late Middle Age (approx. 1300 CE - 1500 CE): The world teeters on the cusp of extraordinary change, as kingdoms clash in bitter conflicts, treasures from eastern lands pique the curiosity of explorers, and a renaissance of thought simultaneously shatters established traditions and gives birth to new possibilities.
8. Renaissance Age (approx. 1500 CE - 1700 CE): From the embers of the past, an era of rebirth illuminates the world, where artistic brilliance flourishes, scientific breakthroughs revolutionize understanding, and ambitious monarchs strive for supremacy, as humanity marvels at the intertwined threads of beauty and progress.
9. Enlightenment Age (approx. 1700 CE - 1800 CE): Radiant enlightenment awakens minds, challenging established norms and fostering the spirit of reason, inspiring revolutions and fostering newfound freedoms, forever altering the social fabric of societies, and paving the way for a brighter future.

These are historical ages in my game. For each of these historical ages, come up with 2 alternative ages that showed an alternative path of human development.
