Dr. Planet

In the distant future, people keep whole mini-civilizations as pets, and they pay a lot of money for them. As an expert in your field, you travel through the galaxy and deliver the best colonies to customers. Casual and relaxing colony simulation inside the laboratory. Combine different mini-planets and civilizations, then put them into the time simulation device for 1000 years. It may not be long for us humans, but for these little creatures, it's eternity.
