Summary: Great game with even better graphics. As others have said the AI is broken. This however is easily fixed by installing the Darthmod. Great game overall and highly recommended. The DLC is also great and adds hours of extra content. The Napoleon add on is a huge improvement over the Empire game!
Summary: I am an avid wargamer and having seen the "ify" reviews of Empire I was very concerned, having tried to avoid steam for so long. Well this is my first try, and I have to say, at times it can be irritating but for the most part it works (I have Comcast WIFI and an i3 core processor). The game itself is much fun with the sounds, music and battle feel (the screen shaking when you take artillery).
Summary: Napoleon Total War is a great follow-up to Empire Total War, that further refines the AI and gameplay. Although you cannot play as the USA in this one, the included Peninsular Campaign of Spain is a hoot and highly recommended and the best part of the collection.
Summary: If you know this franchise then you know what you are getting. It is more of the same stuff. This is one of those titles that will go on sale for the Holidays if you are willing to wait for it. Requires Steam activation but I am actually getting to like Steam. Games eventually become inexpensive so there is little limit to the number I can own and play as long as I am patient. And I can play anywhere as long as I can log into Steam.
