the prolog where the protagonist is old and basically says "everything works out great, I'm rich and have a huge family and let me tell you how I got there" spoils sense of exploration and suspense, especially early on in the book when you don't know where the story will go. One of the reasons I like litrpg (and the larger genre of Isekai) is that the world is totally foreign with foreign rules for the reader and protagonist to explore together. To spoil it shaves off a huge part of this.
Plus I hate spoilers in general.
It also fell into the same "trap" of a lot of litrpg where so much of the character's progress was a bit unearned and the "exploits" he found were too obvious. Stuff like being in a world where a high int score gives everyone Batman levels of memory and an subgroup of people exist for exploitation, but homeboy is going to be the first to discover card counting in single deck blackjack? Or the idea of mob farms, which is something I figured out when I was a kid and played Ultima 7? I've kinda learned to ignore that common flaw that litrpg has and suspend disbelief.
