I don't know why it's taken me so long to remember this, but there's an interesting computer game set in post-apocalypse Russia that some of you might be interested in.
ATOM RPG is developed by the indie developers of the same name. It's set in an unnamed region of the post-apocalypse Soviet Union and you are an agent of ATOM, a pre-war recovery agency.
It's an RPG more in the vein of the Metro or Call of Pripyat franchises than FallOut and there isn't much of a sense of humor in it. I personally found the game fun, but be warned... the combat is brutal.
No, I am not affiliated in any way with ATOM and have no relationship with them other than as a satisfied customer.
