Rome with all the expansions (Barbarian Invasion and Alexander) is probably my favorite, because of the music and the age they take place in, followed by Medieval II and its expansion.
I have all the Total War games up until they were released as Steam exclusive, which made them un-attainable to me as a matter of principle. I lost interest in the franchise when it required a third party, which was an unnecessary move, even though I do have Steam (was lured into it because of Skyrim..).
To be fair, I don't blame Steam (Valve) for what Creative Assembly (Sega) decided, and I do have a few other games on Steam that I might have gotten an account fort, had I not already had one, such as Borderlands 1 and 2.
