It is not a real RTs, it is in the "tactical Real Time" game genres.
Total wars are two games in one. Theres is the Turn Based world, where you throw armies around, conquer territories and such, build castles all that.
In the turn based world, when you want to challenge another army or take over someone else's major city, your go into the Tactical strategy mode, where you move around the armies you purchased in the Turn based section. The Tactical map is fun, but most battles are decided before you start.
the hybridization of the game play elements is pretty cool.
