I recently finished reading 2312 by Kim Stanley Robinson.
You can never say the world building is done by half and there was a lot of that going on. However the plot and the flow of the story suffered because of it.
It's great for reading about some cool ideas about living in space but as a story it was a bit of a chore, especially the last few chapters. The fragment chapters, John Brunner did this way better 50 years ago.
Think Blue Mars in a broader area and no politics
