Jumping on this to second it and also be shamelessly elitist. Factorio is the automation game. Nothing tops it. You may think other games look more beautiful, exciting, or engaging, but they are not. Factorio is also one of the cheaper automation games out there with one of the best developers in the industry. Definitely give it a go!
The flag patriotism and intense praise of military action was a lot for me. I remember going to a mall, and seeing what would typically be reserved as disabled parking was instead veteran parking?? And then the cinema in the mall loudly advertising its discount for veterans as well. We do have a general discount in my country too, but it’s not so… intense. Like no one else has to know it’s happening because it’s more of a state benefit than it is a form of patriotism.
Neighbourhoods in general are what I found the strangest when I stayed in the States. Flags everywhere as you say, but also just the intense size, and the lack of walkability (the kurb drops felt massive compared to my country). Beyond that I remember walking for around 20 minutes through a suburb and counting upwards of 10 different company logos on rubbish bins. This neighbourhood seemingly had 10 different bin days rather than one centralised service.
