Creative Assembly originally planned to make the first Total War title a Chinese game way back in 2000, but during development they became obsessed with a samurai board game and switched the focus of the video game to Japan, resulting in Shogun: Total War. It's taken them a long time and a dozen other games in the series, but they're finally getting back to their original plan.
Total War: Three Kingdoms will be released in late 2018. This is a very busy period for Creative Assembly: Total War: Warhammer was released in 2016, its sequel just a couple of months ago, whilst Thrones of Britannia: A Total War Saga will be released in the spring. Total War: Warhammer III is also due in 2019.
With other games taking years and years to come out, it's good to see one developer releasing games on a much busier and more frequent schedule, as long as the quality remains high.
