Even though Metro 2033 is a very gritty, very bleak and very violent post-apocalyptic game, it is an extremely fun and very useful addition to anyone's video game collection. First off, the language, sex and drug use are nothing high-school freshman haven't seen or used before, so these ratings shouldn't cause any problems. I believe it can teach the players not only how good they've got it and how bad the world can end up if we don't take care of it, but it also teaches conservational and survival skills, i.e. the value of ammunition and health, etc.
Good for adults and kids with mental age of ~15, if they enjoy a game with a heavy focus on a good story
Metro is a good game. Easiest way to describe it would be calling it a S.T.A.L.K.E.R. game with the freedom changed into the storyline. Though it is nowhere near as boring as Bioshock and "Fallout" 3, they do have similarities. Artyom, as a character, is a good man. He does what he must, though both of the endings are a little off-setting.
I am assuming I am the only person here who has ever read this novel. I must say even though it left many bits out (the novel was very long) and some bits were changed to give more action scenes it is pretty true to the original. Its not for small children but older teens and adults should give it a try. Even though it has a very bleak, grim and kind of scary atmosphere you have the option to go through the game being just normal or you can go through being kind and helpful witch gives a brighter more hopeful ending. I loved it.
