From what I understand, there is quite a different feel between the gunpowder-centric, later entries in the series like Empire and Napoleon, and the other titles in the series like Rome, Medieval 2 and Shogun 2. Personally I never felt the draw of the Empire-type titles and stayed well away, plus the critical reception seemed kind of lukewarm too. If you have any kind of interest in the series, I wouldn't write it off totally until you've tried one of the better-received instalments. Having said that, all my complaints further up about DLC still remain.
