The Creative Assembly development team in the UK looks like it is getting ready to announce the next game in its very long running Total War RTS game series. A post on the NeoGAF message board has include a scan from the Australian print magazine PCPowerPlay which seems to suggest that the next issue could be the official reveal of Rome 2: Total War.
In addition to that evidence, Creative Assembly team members will be attending the new Rezzed PC gaming trade show in the UK in early July, where they have promised to show what's next for the game developer.
The original Rome: Total War was the third game in the Total War franchise. It was first released in 2004 by publisher Activision, before The Creative Assembly was acquired by its current owner Sega. The game, set during the ancient Roman Empire, received two expansion packs (Barbarian Invasion and Alexander) and received high praised from reviews at the time. The last game in the series was Total War: Shogun 2, which came out in 2011.
The Creative Assembly is already confirmed to be working on another game, set in the Alien/Aliens movie universe, for its parent company Sega. However, no other information about that game has been revealed.
