Query: Not The Best Game Ever; But A Definite Must-Play

I didn't think this game was the best I've ever played. I didn't think it was the most beautiful game I've ever played. It wasn't the most technically perfect game I've ever played.It's hard to explain exactly what makes this game so classic. I suppose it's just the totality of the story, setting, and atmosphere that really does suck you up. It's a great example of how to integrate sound, graphics, story, and gameplay into a very enjoyable experience.Technically, this game will hone your twitch skills to where you'll never waste a bullet; every shot is a headshot, because you know that you can't waste the bullets, otherwise the dogs will get you.Also, make sure to download the STALKER complete 2009 mod. It brings this game's production valeus up a couple of notches without ruining the essence of what makes this game so definitive.
