Books into...games?

I've been seeing this a lot lately, novels being made into games and thought that it was kind of cool. I mean they've been done in the past, especially if it was something by Tom Clancy, but just recently, Nora Roberts and Marjorie Liu jumped into the gaming world. Maybe I should have said that it's recently that romance writers have stepped into the video game world because there's definitely been a lot of books in the past made into games (Harry Potter, Lord of the Rings, etc). I do have to wonder just how close to the book these games are. Fans of the book are often and easily disappointed into the translation of it just on screen. I'm thinking that it'll be one of those, leave-any-preconceived-ideas-of-book-at-the-door type of thing. What do you think? Like or do you stay away from these type of games?
