Stalker at its best is an unforgettable experience. It draws you into its world and makes you feel genuinely like a scavenger – that your decisions affect this living, breathing world in a very tangible way. This is why I get so annoyed when some Muppet comes along spouting gibberish. It completely kills the illusion, and you instantly remember that you’re sat in front of a PC, not scouring the woods for fodder.
