The Tblisi Ministry of Transport is very constructivist and/or brutalist. Basically, very Soviet. It also bears a striking resemblence to the kind of structures that you’d find in future-set FPS games. Perhaps it’s no surprise that Half-Life 2 is set in an Eastern European styled city.
It makes me wonder if anybody has done (I’m sure somebody has) a study on architectural/civic design as represented in video games. Could be an interesting subject.
