I made a post earlier about this, but it seems ENWorld stopped working for me right when I was posting it. Oh well...

The characters can only act as they are written? Um...yes. That I suppose is correct. I would really be impressed if characters in a written work could act in any way other then how their creator put on the paper. :\ Fantasy fiction as a source is essentially unlimited because you can write down
anything you think of. Few things in my opinion are as unlimited as the written word.
Arn't you holding videogames and books to different standards, then? By this logic, videogames are just as unlimited as books, if not more so (since books, at least, require you interact completely with text and static images, which is not a requirement for videogames). Game designers can make anything they can think of, and have unlimited possibilities for gameplay and story.
From the perspective of creators, both videogames and books have unlimited options and potential. From the perspective of players and readers, the experience is completely determined by how the creator permits the reader to interact with it. In both cases, there tend to be more options and flexibility in videogames.
Either way, the "freedom to do whatever I want" is a pretty bad thing to measure different forms of entertainment by. It is completely unrelated to the enjoyability of any particular medium, and few things even hold it as any form of ideal. Why measure most videogames by their ability to create an infinitely varied sandbox experience, if so few of them even hold that as a goal to achieve, and most are very enjoyable regardless? Actually, I tend to think that the infinite sandbox is a pretty boring experience, in games and in D&D itself.
Also, the only infinite sandboxes you seen in books or movies are blank pieces of paper and blank rolls of film, so I doubt those mediums would want to be measured by that odd ideal either.
Can mods add original content and dungeons of your own design to the crpg you're playing?
Yes, that is the entire point of a mod.
