TV limited series adaptations of The Culture novels. Amazon obviously made a start before giving up but they picked absolutely the wrong one to start with.
Yes Consider Phlebus is the first chronologically but a TV series where you have to replace the main character every episode does not work when you are already trying to adapt a very difficult IP. Player of Games is where you want to begin. Clear storyline, no tricky time/universe/world jumps. Spends most of the time in an Earth-esque civilization. If you can successfully adapt PoG then you can try something more challenging like Phlebus or Use of Weapons.
