That's a pretty BS article written under, what appears to be, some sort of assumption of how life in Soviet Union was all driven by communist ideology. Hardly any games had "Marxist agenda", lots of them had high scores, and you bet that the adrenaline rush was right there. They weren't designed to train loyal citizens anymore than Mortal Combat was designed to train hand combat. They were just games... heavy and crude, but they were designed for fun first and foremost.
