The PCGamingWiki is a British-based[1] collaboratively edited free wiki internet encyclopaedia focused on collecting video game behaviour data (such as save locations and startup parameters), to optimising gameplay, and fixing issues found in PC games.

The wiki site runs on MediaWiki software, and was created by Andrew Tsai,[2][4] a British businessman from London, England.

[3] Since its inception, the PCGamingWiki has been featured on numerous gaming focused websites, including Kotaku, Destructoid, and Rock Paper Shotgun.

Tsai was motivated to create the wiki based on his experiences with the games LA Noire and Titan Quest.

[11] In April 2020, the wiki launched new categories to track a game's monetisation model, including the types of microtransactions present.
