Unmistakeably Unbelievably Unprecedented!
The developers have built upon the success ETW's predecessors introducing several new features, most notably the face blisteringly awesome naval combat, in addition to streamlining and refining some features which bogged down the earlier titles. They have also introduced a new campaign in addition to the grand map that follows a choreographed storyline through the United States' pursuit of independence. This allows for a beginner or veteran to become better acquainted with the new controls and strategies and to be entertained by a fantastic tale with glorious cut scenes.
ETW is, as most feared, riddled with minor glitches and frustration inducing flaws but none really take away from the overall experience. The AI pathfinding has its comical moments amidst the chaos of battle and sometimes units have trouble coordinating their attacks. However, both the battlefield AI and campaign map AI is highly polished and refined in comparison with MIITW, especially on the campaign map where sometimes you'll think you're playing a human opponent.
Now excuse me while I get back to my Total War marathon.
