Well Though Out, and is easy to play with.
For a game, that came out quite a bit later that I would have expected, is still a shining star today.
There are so many different types of ways to build a city, build your industry, economy, etc.
What bugs me sometimes though, is that you have to go out of your way, to order (for instance: Sculptures, to get a hero to come to your city) Which costs a fortune.
