Total War RTS franchise from developer The Creative Assembly and publisher Sega. A Turkish web site has apparently gone off the reservation by reporting that it was to be shown Shogun 2: Total War at E3 next month.
And if that's not enough, Voodoo Extreme has posted up what they have said is a full press fact sheet for the game which according to them is slated for a 2011 release. If true it would certainly be a "back to basics" move for the developer since the original Shogun: Total War was the first game in the series. It was released via published Electronic Arts way back in 2000.
