Taking to the Total War blog, Creative Assembly has announced a new class of Total War games -- Total War Saga. Which, will be a series of standalone games built from existing historical time periods already visited by the series. Like Napoleon and Attila, these games will focus on single moments or periods in history with the studio pointing towards Rome as one of the first stops for Total War Saga.

Total War Saga games will be the same mix of turn-based campaign strategy, real-time battle tactics and hundreds if not thousands of hours of gameplay as a regular Total War game, but focussed down on a distinct moment.
 
Sagas won’t be revolutionary new titles or introduce brand-new eras; they’ll follow-on from previous Total War games and inhabit the same time-period, or at the very least relate to it. But these are certainly Total War games.

The Saga branding is to ensure that players are aware that these games will be spinoffs and not the next major Total War titles. And when you add in Total War Warhammer 2 coming later this year plus word that the team are working on a Total War set during a time period never before explored by the series, then it sounds like Creative Assembly are working on a lot of Total War stuff right now.

Which is very cool.

It's expected that the first Total War Saga game will be released before the next big Total War proper.
