If you read the metro 2033 book I want to ask you something

I'm pretty sure there is 2 books, might not be right though. There may be more also, but I think 2 books separate the 2 games

Edit: I think i'm wrong

There was a Metro 2033 book?

Uhhhh very loosely. The broad events are the same (the Dark Ones, Artyom) and the ending is basically a fusion of both game endings, but most of the events in between are pretty different. The book isn't very violent. But both are VERY psychological.

My class mate is reading this book, which is extremely irrelevant information, but maybe someone cares ;)

Don't be silly, the game isn't base on the book, it's based on the "Little metropolitan builder" cereal that was produced in USSR in 80's.

Yes there are many books and the game is not really based on the book, but more based on the world that the book takes place in. There are many other books, but only 2 in the series from Dmitry Glukhovsky. Those main two are in German, the first in English and all (including the universe books by other writers) in Russian.

There are few thing book is telling in more details than a game, but there is a lot of inaccuracies between game and book. Book is better. But game is good though.

Last Light will be between Metro 2033 and Glukhovsky's new book

AFAIK, upcoming metro doesn't follow the plot of neither 2033 or 2034 books, but rather it's own. Still, Glukhovsky was involved in making of last light, so the plot should still be connected with books in some way.

Didn't play the game, but I know that the -------SPOILER-------- bad ending of the game is exactly like the ending in the first book, and that some missions are taken from book, like nazzis and worm mission I think. I'm just guessing, but I watched the ending of the game and I've seen the achievements, but I have read the book.

It's not really based upon the book. Book is more about the nature of a man, game is more about action and horror. Book has slow tempo with lots of philosophical references and makes you think, while game is fast and makes you react. I would say game is based upon the world of the book, not the book itself. The main story is somewhat the same, but then again, it's not even close. Depends on what you, the reader/gamer, find important.

The Metro 2033 book ONLY covers Metro 2033.
But the book from Metro 2034 (The Sequel) isn't actually part of Metro Last Light

I didn't really go that far into the game, but in the beginning it follows the book quite closely, later on it starts to differ... i.e. i remember a good chunk of action above ground, but in the book it's way more dangerous to stay outside, and 95% of the time Artyom stays in the Metro.

The new game has a storyline specifically written by Glukhovski, it has little to do with either book.
