eFootball (formerly referred to as Pro Evolution Soccer and Winning Eleven in Japan) is a series of association football simulation video games developed and published by Konami since 1995. It consists of eighteen main instalments and several spin-off style titles that have been released on many different platforms. The series has consistently achieved critical and commercial success.
eFootball has also been used in esports. eFootball.Open (previously named PES World Finals or PES League) is the esports world championship held by Konami annually since 2010.
In association football circles, eFootball has a longstanding rivalry with EA's FIFA series. eFootball is the second largest association football video game franchise after FIFA, with the rivalry between the two franchises considered the "greatest rivalry" in the history of sports video games. Listed as one of the best-selling video game franchises, the eFootball series has sold 111 million copies worldwide, in addition to 400 million mobile game downloads, as of December 2020. Konami also created a similar mobile game called PESCM or Pro Evolution Soccer Club Manager.
