The SSBPD, short for Super Smash Bros. Player Database, was a website for ranking the relative performance of Super Smash Bros. Melee players through an adaptation of the Elo rating system. These scores were determined by Tio files uploaded by tournament organizers; as a result, there were hundreds of players on the registry.
The SSBPD was discontinued in Summer 2012 due to the reduced use of Tio, and a few months later, the database later went offline. As a response to the discontinuation of the SSBPD, Melee It On Me created the SSBMRank to rank the world's best Melee players, though this ranking relied on a group of panelists instead of Elo scores.
