Civilization III will rock your world!I enjoy playing Civilization III.
My rating is a 9 out of 10. The only draw back is that it makes you retire at 2050 AD.
This is a good game for 10 and older. It takes strategy and you have to know when your stronger or weaker than your enemies or, when to attack or, when to sign a peace treaty.
The more technology advances you make the better units you build. Don't forget to build curtual achivement or the people will rebel against you!
