So this series is clearly a wish fulfillment storyline for the author.
Despite the fact that the character has 1s in every stat, which the author refers too constantly in the work as being pathetic, he survives an attack by a wolf many levels higher, outruns said wolf, then jumps into a tree and climbs fast enough to get away. Later dropping down on the wolf and killing it.
This (I win) process continues throughout. Even when the protagonist loses he wins.
The Mary Sue trope was so prevalent it reduced my ability to enjoy the story
The game aspects of the novel are clearly the input of someone who has not played many, if any, mmorpgs. There are inconsistencies in the “rules/logic” and poor conceptual designs that are unexplained. If you like the game portion of litrpg you will be disappointed. These were clearly inserted to market the book as such.
Finally the Harem aspect. This is clearly a harem book. The authors unsubtle statements from the character to the contrary are ridiculous. Simply note that all the primary characters other than the hero are women and fall in love with him and… of course they dont start having sex until another book. So even if you enjoy subtle misogyny and harem stories you will be disappointed.
