Edit: 5 stars--> 1 stars
Series seems abandoned, last book was 2022. By looking at his website, he appears more interested in running a vanity hotel for 'creatives.' No point in buying a dead series, or one that only gets an update twice a decade. One of us will die before the series ends.
FWIW, it's a pretty good "standard" litRPG. Nothing surprising, but the world building makes you want more. I liked it better than Ether Collapse, debruyin's other series, which is on book 5 and seen by many as a signpost of the genre.
