Drawing from the fundamental principle that "people play games together", Koster and Butler predict a huge shift in the games industry as the impact of online gaming starts to really hit home. Butler's claim that "linear entertainment in single-player is to media what masturbation is to sex" is eerily similar to David Jaffe's comparison between games and porn. Experiences are enriched by the presence of other people, and perhaps the depth of multiplayer gaming and the online social interaction embodied in these games can provide the emotional content that Jaffe finds so lacking.
