First section would be about how existing as a tool for corporate profit harms the medium. It’d talk about things like concentration of the industry under a handful of companies, predatory microtransactions, the rise of subscription-based platforms where players never really own the games they play, how series like Call of Duty serve as propaganda for the American military industrial complex.
Second section would discuss how video gaming might be different under socialism, based and my own experiences with other nonprofit hobbyist developers - artistic expression over spectacle, an end to predatory monetization models, making the hobby accessible to people who can’t afford expensive consoles or gaming PCs, etc.
You could also have a section about the recuperation of mods (free/hobbiest) into the corporate model. This has happened numerous times. The big examples would be Counter-Strike and Battlefield 2, but I’m sure there’s more that could be cited. Maybe the minecraft saga could be another case study with the infiniminer code base etc.
There’s a lot of rich areas for analysis of games, game cultures, ludology under capitalism, pay to win, etc.
