That's the bad part that is bothering me. Did they replay your whole life once you died and gave you some score for each event or decision ? Who established the rules and the scoring ? Would it change with societal change in a given society ? Could you evaluate yourself at any point if your life to see if you were a "good" or "bad" person ? Could you hack the system by implanting false memory ? Or could you wipe out some embarrassing parts? You could write a book on that topic only.
I agree those are interesting questions not directly addressed by Surface Detail.
However, on a related topic the novella A Colder War by Charlie Stross has a particularly creepy ending if the idea of virtual hells bothers you - the idea that an intelligent entity actually enjoys running simulations of minds and exploring the ways they can end:
There is life eternal within the eater of souls. Nobody is ever forgotten or allowed to rest in peace. They populate the simulation spaces of its mind, exploring all the possible alternative endings to their life. There is a fate worse than death, you know.
