Only get if you have a powerful gaming PC.
PRO: Excellent 3Dgraphic gives a whole new dimension to the game view. Game menus and interface are very good and easy to use especially if you played CIV 1-3. The helpful advice throughout game in different forms is good i.e. where to send workers. Individual units are excellently done. The different types of government and civics menus and selections are outstanding and add a verity to the game. The diplomat screen and actions are a vast improvement over previous games.
CON: Game requires a powerful PC to play must have 1.0 GB RAM and over 2.0 GHz speed and current 3D video card. Before I updated my PCs RAM the game would slow down at the middle going into the end with large map and above. The SPY unit really isn’t good for anything other then exploring. Music volume is control by zoom the closer you zoom no music. Still no in-game delete function. The Play now selection should have a way to set the game win conditions instead of always having to use custom.
It you have a powerful enough PC I would recommend the game for all CIV and strategy fans.
