You probably haven’t played one of the most important games of the year yet.

Released quietly this past summer, 1979 Revolution: Black Friday documents the violent and tumultuous Iranian revolution of that year. It’s a game that is as much a documentary of record as it is an entertaining narrative experience. Ink Stories founder Navid Khonsari says the indie developer is trying to invent a new genre with 1979, one that combines the thoughtful research of documentary film with the interactive possibilities that video games offer. By all accounts, they have succeeded.
