Sengoku Basara, Sengoku Musou Recommendations
they are based on Hack n slash games that are based on the warrior states period. Sengoku Basara is more over the top and intentionally historically inaccurate, where as Sengoku Musou is more focused on the historical side of the period.
These are both over the top historical fictions based around samurai. Sengoku Musou is not nearly as wild, but it is based on the same time period even sharing several characters between the series.
