Books into games

Here’s a question, how come books aren’t adapted as games? I mean all the books that have been, were first made into movies, and then, they were more of a movie adaptation, than a book adaptation, which isn’t the same thing. Seriously, they’re tones of books out there that could be made into awesome games, but why don’t people look in that direction?

Guys like Sherlock, or any of tolkein’s characters from not the movies could work. I mean it LOTR has its own series of games, why can’t The Hobbit have one?

I’m not sure, but this huge divide between print and visual media, to me seems pretty artificial, and is causing a lot of people to loose on a lot. I’m not pleading the case of graphic novels, but I feel, there is a lot that can be done with many thigns, that so far have been ignored, simply because they’re print…
