Actually, it may be strange, but I think I have had considerably more fun replaying the game 2nd, now 3rd time than I had playing it first. The same thing was with Thief. I guess it's because game mechanics, and world are deep enough to guarantee you won't be able to learn it entirely during the first run through and even maybe second, and when you already know relatively good how it works, layout of the maps, your enemies, what to do and when, etc. you may concentrate on fun and experiments. I can't think of any modern game with more complex game mechanics and AI system than Stalker has.
