My first experience was the Ready Player duology by Ernest Cline and the This Trilogy is Broken 4 book series by JP Valentine. I’ve also had many recommendations for Dungeon Crawler Carl by Matt Dinniman.
The Ready Player series was basically an ok story with a “hey, remember this thing from the 80’s‽” through-line. And while some of the jokes felt forced, the Valentine Series overall was a ton of fun and I couldn’t stop reading it.
What else have you really enjoyed? (This genre lends itself towards a couple of Bingo squares too. )
I think you should looking for xianxia genres.
Xianxia is gamelit, but in the opposite way :D because the book usually write long before game is popular, and game follow their concept.
Usually, xianxia is like you play rpg, you farm or quest, accumulated resources (which you can consume directly, or exchange for pill and drug and food that you can consume, or weapon, manual), then consume resource (i.e: spend hard-earn money to make you stronger), then get stronger, level up, beat the boss (optional), go to next map, repeat.
But usually the whole novel is an interesting journey without too much of repetition.
