Not OP but I've really enjoyed the He Who Fights Monsters series by Shirtaloon and Orconomics: A Satire by J. Zachary Pike.
First hour or so of HWFM was a little rough, but then it hit its stride and here I am 9 audible credits later, ready for the 10th to be out. Was entertained the whole way through.
IMO J. Zachary Pike has better writing technique, but hasn't released as much. I'm presuming the extra polish costs more time to author.
(I have read and enjoyed a couple of LitRPGs)
