Out of context
In this scene, the Computer Space console features prominently as part of the narrative exposition that establishes the class disparity that frames the film. Cutting inside after a painfully squalid exterior scene, a slow pan highlights the ostentatiously open spaces of the apartment living room where the console has been installed; a young woman in a long dress (which closely resembles that worn by a model in a magazine advertisement for Computer Space) plays the game gleefully when her aging husband enters the room and expresses pleasure that she is amused by her new "toy." This environment is starkly contrasted with the previous scene on the streets outside which are littered with abandoned vehicles and homeless bodies. In this fleeting moment of Hollywood history, ownership of a home video game system signifies high class status and an extreme of wealth and privilege. It is also worth noting that Hollywood's first video game player is a woman who proudly declares her prowess in the game as having "demolished five saucers with one rocket" (an impossibility in the real world Computer Space game). This announcement, in turn, marks the generational separation between the woman and her wealthy benefactor as she transitions to a relationship with a younger man.
The following year, Alan J. Pakula's The Parallax View (1974) featured a brief scene with a Pong arcade console, which was likewise dislocated from its commercial context -- in this case as part of a behavioral science research lab. The novelty of using Pong for primate research in the early 1970s constitutes a prescient view of the potentials of games for psychological research, but was most likely included for high-tech ambience here. The university research lab presented in The Parallax View is devoted to studying extremes of violence and sociopathic behavior that turns out to be instrumental in a reporter's (Warren Beatty) investigation into political assassination. Like the female game player in Soylent Green, the chimpanzee in The Parallax View is meant to be perceived as a proficient game player (though the actual scenes of game play in both clips reveal the opposite). Both of these instances of game play suggest that the filmmakers confidently assumed a lack of literacy among audiences about the games being played. We may infer that the very presence of video games on screen in 1973-74 was sufficient to signify high-tech futurity, albeit in cinematic futures marked by paranoia and social decay, where women and chimpanzees are the primary players of video games.
