While I'm also not a huge fan of this way of writing, it works very well as a supporting device for me. You have a lot of room there for world building, and the people interested in it read or listen to all the scraps and everyone else can skip them if they don't care. Games can put a lot of world building into optional areas or pieces of content that e.g. would never fit into a movie or even a TV series.
