1. A system for providing searchable short motion sequences to game developers, the system comprising: a communication module configured to receive captured motions of a plurality of game participants through one or more capture devices; and a server configured to: determine frequently requested motion segments; search a captured motion database for the frequently requested motion segments; identify one or more frequently requested motion segments lacking from the captured motion database; issue a request to the game participants to provide motion including the lacking motion segments; receive the captured motions in response to the issued request from the communication module; filter undesirable motion segments from the captured motions; generate searchable quantizations of short motion segments from the captured motions; add the searchable quantizations to the captured motion database; and render the searchable quantizations available to the game developers from the captured motion database.
