TL;DR I am absolutely going to buy the next one.
Alternative title: What if Dennis Vanderkerken experience isekai?
What I know of the author Dennis Vanderkerken I only know from his books and from Dakota Krout's origin story about how they met. It's probably all mixed up in my memory but I think that Dakota Krout was contacted by this guy who told him that he was missing all of these amazing details about the Divine Dungeon world Krout had created and gave him all of the spreadsheets and logical deductions evidence to prove it. And Krout said well write it all then. And thus the wild excrutiatingly detailed 19 books of the Artorian's Archives. It's full of love, brutality, comfy pillows and insanity, not to mention wild insane geese, ever-altering realities, dread gazebos and secret cow levels.
I think this new series is the story of the author himself going through a similar journey without the limits set by an existing series. The beginning is a fast dunking in a lake, but if you learn how to swim it is worth it in the end, even if in some spots you wonder what is making the water warm or cold right there.
The main character is a detailed obsessed ADHD laden man who loves gaming and hidden exploits and just wants to get along with everyone, except those who opose him and must be destroyed. At least that's how he plays his games. And if the world he finds himself in thanks to a door that appears in his ouse is guided by gaming rules, then his course is clear: figure out everything, find every exploit, reward those who help you, crush those who like crushing others.
The cover immediately reminded me of a Stargate and as the next book in the series has the second symbol lit up on the cover, I suspect there will be 12 books in this series and each will focus on a new world or system. This echos the set up of Artorian's Archives, and with a reasonable number of books in the series. I stepped away from the AA series when I wasn't sure if any progress was being made to a conclusion. This series has a set size and is a known investment.
If the next book were out on audiobook, I'd have started it immediately.
