The document discusses strategies for preserving virtual worlds and games, including bit storage, migration, emulation, and re-enactment. It proposes using the OAIS reference model combined with FRBR to create a data model for preserving games and their derivatives over time while maintaining associated metadata. Legal and financial challenges around copyright and orphan works must also be addressed to enable long-term preservation of games.
