Video Game Artbooks

Now you might be wondering what i'm even referring to with this topic. Well let me explain. Once and awhile i tend to get these limited edition copies of games, that tend to come with a bunch of cool bonuses and what not. Now there is one bonus that tends to be in almost every limited edition copy of a game. I'm obviously talking about Artbooks. Artbooks are pretty straight forward, they showcase the concept art of the game you just bought with some notes from the artist developers of the game, stating if there were any changes, or what each concept represents. I find these Artbooks really interesting and stunning to look at. What about you? Do you guys read any of the Artbooks of games? Would you read the Artbook if it came with your game?
