Koei has performed various third-party collaborations with their products. Consumers can often participate in them by inputing registration codes with a related product. These registration codes can be inputted online through a personal computer or mobile phones to unlock various bonuses for a game. Usually, these codes can be inputted with a Mobile Joy like method. These bonuses are exclusive to Japan.

This list will also strive to include other miscellaneous third party media that don't employ inputting a code into a cell phone. It will also combine expansions packs and spin-offs with its parent title.
