-// serialization service: serializes changed world data and ensures that the database and any loaded data are in sync such that the database can never be more updated than loaded data, also performs compression on serialization
-

-//player tracker system (determines what lods are loaded and used by the player)
-//updating system (triggers render data rebuilds when something from the ingest service causes an LOD change)
-//the render system simply renders what data it has, its responsable for gpu memory layouts in arenas and rendering in an optimal way, it makes no requests back to any of the other systems or services, it just applies render data updates
