Edit - Lotta video game apologists in this thread. Look past your capitalist dependency on causing violence to other people/animals, and recognize what you’re doing. Stop Video Games.
Video Games are a media (superstructure) that reflect the economic base we live in. It is part of the cultural hegemony we live under, that the state uses to justify itself and capitalism.
Violence is an inherent part of this ideological propaganda apparatus (along with patriarchy, racism, sexism, transphobia, homophobia, anti-communism, capitalist normalization etc.)
All media influences the people that receive it. It is “pure liberalism” to believe it does not. If you’re a Marxist, you must stand against video games under capitalism.
F.E.A.R. is a good example of this. The AIs use a relatively simple set of rules-based commands that result in complex emergent behavior. They’ll do all kinds of cool tactical shit that looks like planning and intelligence to the player, but under the hood it’s governed by a couple of rules like “seek cover” “shoot at the player” “circle around the player”.
