We humans are becoming an urban species, so cities, they are our natural habitat. That is where we live. In 2014, over 54 percent of the world population was living in cities, and I can bet you that so many of these people have thought of how they would do things differently, like if I only had the tools to change things in my city, what would I do? What would my dream city be like? And these tools, this is just what we gave them. Two years ago, my team and I, we released a game, "Cities: Skylines." It is a game about building cities.
So I have always been interested in cities as systems. It's something that I find immensely interesting. But what I didn't understand was that I am not alone in this. People love cities. They are interested. They have ideas. The game was an instant hit. So far, over three and a half million people have played it.
