* "Fictional websites", "marketplace", and "business creation" refer to game features that occur locally on player-hosted game servers. The marketplace is fictional and does not use real currency; it is not accessible outside of the server it is hosted on and should be considered a novelty interface.
** "Content updates" refers to changes to the ProtoMasons game that are delivered as updates via the Steam client. Content updates may include one or more of the following: bug fixes, the revision or removal of game features, the addition of new game features.
