The retail guides for Dark Souls and Soulcalibur V were fantastic. I like a well-done guide, even if I don't really use it. I got the guides for the last two Zelda games after I had finished either of them simply because they felt like collector's items. I'm a collector. I kind of like having the art as well, since we don't often get proper art books for most of these games. I have a few 'proper' Japanese art books for some games I have too.

In fact, if a game has art that I find appealing and it has a separate strategy guide for purchase, I'm pretty likely to pick it up just for that. Thankfully, folks like Atlus actually include art books with their games.
