I can think of some obvious examples to start with, but my subtle but insidious nominee is Fable III. Fittingly for a pretentious grifter like Molyneux, the game requires you to raise a specific amount of gold or your kingdom is destroyed and you get a bad ending. The goalposts are moved by the game if you raise money in ways it doesn't approve of, and it is simply impossible to reach the fundraising goal in any way that isn't at least Enlightened Centrist levels of evil, the kind that lanyard-wearing neoliberals giggle about. That's right, you need to be at least this evil or your kingdom is destroyed. So deep and really makes you think about the hard decisions that are made by the ruling class, doesn't it? :zizek:
Yeah there's absolutely nothing subtle about these games, it screams it's message in your face. There's probably some galaxy brain G*mers out there though who'd say oh the CoD series is very subtle propaganda, you can just ignore most of it :agony-yehaw:
