While I like the idea of friction in video game spaces, especially when it promotes a sense of place - but aesthetically I kind of bounce off Brutalism (as an architectural style) hard. As an architectural style, it feels extremely totalitarian. It’s like something that would be invented by an architect who fell through a portal from Airstrip One into our world, found a job as an architect here, and came up with the Brutalist style because The State had ground the ability to do anything else out of them.
So, if a game is using Brutalism to help show how the world the game is set is a totalitarian dystopia, then that will work for me, as that heightens the sense of place. However, if it’s just as a general anaesthetic choice, then for me not to bounce off, the game would have to present some sort of really spectacular mechanic or narrative to keep me hooked.
