You got it wrong. (again)
Once again, commonsense falls short on another great game. STALKER's corpses are indestructable; I tested this myself. I bought a heavy machine gun from a faction (for several thousand rubles, the currency in-game) and unloaded 2 full boxes of 7.62 into a bandit's body. I also threw a couple of grenades and it did jack shit. The artifacts aren't 'magical,' they're altered by the conditions of the alienation Zone.
STALKER: Shadow of Chernobyl puts you in the badly-made boots, jeans, and leather jacket of the Marked One, an amnesiac STALKER (An acronym used by the military and other Stalkers: Scavengers, Trespassers, Adventurers, Loners, Killers, Explorers, Robbers.) who was rescued from a 'death truck' that carries corpses and near-dead people towards the center of the Zone. These trucks are absolute mysteries, so it's a miracle you're alive. All you have is a pair of binoculars, some clothes, and a strange man who tells you that all that was on your PDA was two words: "KILL STRELOK." Strelok is supposedly a man who made his way to the center of the Zone, and you were, for whatever reason, hunting him down. On your way to capture (or kill) Strelok, you must dodge robbers, killers, mutants, Anomalies, radiation, and the mysterious Monolith faction. The story twists and turns and you can choose to take optional quests. There are factions of STALKERs in the zone, such as: Duty, a paramilitary faction that keeps people from exploiting the Zone. Freedom, Duty's mortal enemy, which tries to get the Zone's restrictions removed. The Mercenaries, a group of for-hire killers with unknown clients that have unknown intentions. The Bandits, who are thieves and killers. The Monolith, a cultist group that 'protects' the center of the Zone. And the Loners, your average person. STALKER's story isn't the only good thing about it; the atmosphere is incredible, and I would prefer it over any other game when it came to immersion. The most popular modifications on the internet focus on atmosphere, and immersion, and that tells you just how important it is for this kind of game. Over all, commonsense got its review wrong. Parents may not like it, but STALKER tells a story equal to games such as Half Life. DISCLAIMER: I'm not saying you should give 5-year-olds the keyboard and mouse with this game and tell them to go nuts. I understand that the amount of violence in this game is concerning for parents. At age 10, or maybe 12, they should be able to start on this game.
