DoC: Dawn of Civilization is a game that allows you to learn a variety of skills.

It offers you a fun way of learning that doesn’t require you to spend a lot of time in class. With it, you can learn a new skill in 16 minutes, even if you’re not that good at it yet.

The game is like a mini-course that you can take on your own time, at your own pace. You don’t need to be in a classroom to take it.

DoC is based on artificial intelligence. It’s a game that’s designed to help you master any subject faster and more effectively.
