Dynasty Warriors

Dynasty Warriors is a series of tactical action video games created by Omega Force and Koei. The award-winning series is a spin-off of Koei's turn-based strategy Romance of the Three Kingdoms series, based loosely around the Chinese classical novel of the same name.
The first game titled Dynasty Warriors, Sangokumusō in Japan, is a fighting game and different from the rest of the series. All English titles are a number ahead of their Japanese counterparts due to the English localization of naming Shin Sangokumusō, a spin-off of the previously mentioned Sangokumusō game, as Dynasty Warriors 2.
It is Koei's most successful franchise. Including its many spin-offs, 18 million copies of the Dynasty Warriors series have sold worldwide by 2011.^.
The first Dynasty Warriors is a traditional one-on-one fighting game, released in 1997 for the PlayStation. Its gameplay style is reminiscent of Virtua Fighter and Tekken with the addition of weapons and some exotic moves.
The next game was released in Japan as Shin Sangokumusou. This game was released in other countries as Dynasty Warriors 2, leading to the discrepancy in title numbers. From this game onwards, the player chooses a playable character and plays a number of levels representing particular battles in the Three Kingdoms period, eventually defeating all other rival kingdoms and uniting China under a common ruler. In this game mode, known as "Musou Mode", the generals are usually chosen from one of the three kingdoms (Wu, Shu or Wei; however, from Dynasty Warriors 3: Xtreme Legends onwards, independent generals were given full stories as well). Dynasty Warriors 3 has two secret characters, Nü Wa and Fu Xi, that are not playable in Musou Mode.
Dynasty Warriors 3, Dynasty Warriors 5 and Dynasty Warriors: Strikeforce have individual Musou Modes for each character. In Dynasty Warriors 2, Dynasty Warriors 4, and Dynasty Warriors 7, each of the Three Kingdoms have its Musou Mode, in which all characters from a particular kingdom will play the same mode. The stages are presented in a third-person view, with the camera set behind the player as they engage the enemy forces. Each scenario can have different win/lose conditions, but the common losing conditions (defeat of the commander-in-chief, health bar reaching zero and maximum time limit reached) still hold. As for the other characters not from either of the Three Kingdoms, their Musou story modes are purely fictional since in Romance of the Three Kingdoms, most or all of them were eliminated until only the Three Kingdoms were left.
