Personally I found the connection between Doom/video games and Margaret Thatcher /neoliberalism to be pretty weak. Individually, both points were great and very well stated. And the end conclusion was also pretty cool - unions failed to prevent neoliberalism so they may not be enough to defeat it today either but that doesn’t mean they aren’t a step towards rebuilding the kinds of communities that can.
Edit - also, if you want to draw in “apolitical gamers” they maybe that section talking about how the annoyances and problems people have with modern gaming come from capitalism should be presented before the political talk about neoliberalism.
