Hmm, I do not agree that a computer game - which is an interactive medium - should feel like a book, which is not one. I do think games can learn a lot from both movies and books, the writing quality in games is generally not very good and can be markedly improved, but I don't think that games should feel like books, they should feel like games. With that being said however, the complaint raised in the OP seems to be pretty reductionist and gives a flawed representation of fantasy writing. Terry Pratchett is a fantasy author and a pretty damn good one, I would say when it comes to storytelling, his books are the ones which Larian games remind me the most of. Just because a fantasy novel does not have the tone of say a book written by Brent Weeks or Sanderson, does not mean it isn't a fantasy novel. Not every book or game needs to have the same tone and you can tell an excellent story with a satirical and whimsical tone, which Pratchett illustrates very well.
