Samurai Warriors
Probably the third most recognized franchise of Koei, "Samurai Warriors" ("Sengoku Musou" in Japan) series, was introduced in 2004. Instead of the Three Kingdoms era, the series uses Japan's Sengoku period. As a result, the game's roster consists of characters from that era, while having gameplay similar to that of Dynasty Warriors. The game would be followed by "Samurai Warriors 2" in 2006, "Samurai Warriors 3" in 2009, "Samurai Warriors 4" in 2014, and "Samurai Warriors 5" in 2021. as well as numerous other spin-off titles. As with the original series, "Samurai Warriors" also has the "Xtreme Legends" and "Empires" expansions, with the former beginning on the first game and the latter on the second game.
