Rekoeition Game or REKOEITION (リコエイションゲーム) is a general label for a series of KOEI games; the label appeared during the opening sequences for the listed titles.
Despite their different settings, these games merge tactical simulation and role-playing game elements and grants a certain degree of freedom for each entry's protagonist. "Rekoeition" is a portmanteau of recreation and Koei, a general theme of re-imagining the genre or setting featured in each title.
The producer for a majority of these titles was Eiji Fukuzawa. Its usage was discontinued by 2004.
