mystikmind2000: I like Total war2.... i believe there is a newer game in the series but i remember reading about it and decided there was something about it i did not like, so i never bothered to buy it.
My prefered game in the TW series remains Medieval 2, with its kingdom expansion ( the American campaign in particular)
You should try some of the other games though
Shogun 1 and Medieval 1 are obsolete.
Many will tell you that TW:Rome is better than TW:Rome 2. For my part, I have mixed feelings on that one, but in the end, I would indeed replay the first rather than the second.
I really liked Napoleon. It plays differently, indeed, due to the prevalence of rifle units and to the importance of artillery. It fail in the grand strategy by lacking enough complexity to re-create war preparation in a pre-industrial age, but plys very nicely on the field, in in the smaller campaigns. Empire, well, is probably the weaker part of the lineage.
Shogun 2 is superb, and plays very well on the strategical level and on tactical level. Again, it plays quite differently than other games in the series.
