The patent gives a few examples of how such an idea could be implemented, starting with a single-player game in which the player's actions impact the characters and environment of other players enjoying the same single-player game. As the filing suggests, that would offer players some of the benefits of a traditional online world without a potential drawback inherent to massively multiplayer online games.
According to the patent application, "Those who want to play games that are more dynamic, not-based on Al and not-pre-scripted like multiplayer games, however, don't want to 'deal' with other people, appreciate the privacy it provides."
