@fastfinge also, you can pack stuff from RoyalR into .mobi files and read on Kindle

@fastfinge I've got you. I think.
Not sure which ones go to #litrpg and which ones to #progressionfantasy , but there were few that stood out:
Wandering Inn - definitely off beat main character
Quest Academy,
Return of the runebound professor,
Ascension of the street rat,
The runic artist.
Mother of learning?
All series, should be on KU.
Cradle, and The stormlight archive get a bit stale after n-th book, but first ten should be okay.
