I have played every total series title and the answer to your question is yes yes and more YES YES YES!!!
Essentially the campaign map is all turned based but the battles are real time. You manage you family lines, trade, diplomacy, agents (spies, priests, champions and the like) research and upgrade your technology etc etc.
Battlewise there have been some complaints about the AI, however, it was really just wish siege battles and with Attilia it was MUCH improved!! Espeically with the expansion, The Last Roman even the AI on the campaign map has seen quite a lot of improvements. CA has done a good job with all of their historical titles and this is the VERY FIRST time they have delved into anything that wasn't historical based so its a big leap for them same with magic and flying creatures. Though I am very excited for this title and keeping up with the developers are listening to the community and apparently GW gave them two of each model type so if you haven't noticed they are almost dead on with the current models.
