Good idea. I've re-dipped in some obvious ones recently, like The Road (book + movie) and Stalker (game + movie). Also trying out the most recent Metro game, but I'm finding it a bit limiting.
Again, similar elements to The Labrynth, but mostly missing the retrofuture sci-fi stuff.
Slightly less relevant, but over Christmas I watched Y:The Last Man and Anna, which are pretty meh and pretty okay respectively.
