Sim games tend to either focus on realistic physics and sciences, such as Kerbal Space Program, or a more casual approach, such as Spore.
Birthdays the Beginning is a life sim and god game that successfully straddles the line between the two philosophies. It uses the real-world applications of geology, temperature, and ecosystems to craft a diorama of life. Everything is wrapped within a cute veneer of youthful colors, relaxing music, and playful designs to create an intuitive entry into learning about life’s delicate balance.
