"The first Defier" JF Brink. Typical LitRPG. The world is suddenly subjected to "the system". Monsters are everywhere and you grow or die. Survivors discover "the interface". With it they can level up their stats (like an RPG game). MC is subjected to some random horrible luck where they should have died (most overused trope in the genre), but they survived and became unusually strong. First couple of books are fine. Not my favorite but enjoyable. Last few books are less so.
"He who Fights Monsters" Shirtaloon
Different trope (MC gets sucked into different world where stats and leveling up are normal). Same other than that. First 3 books were great. Middle books were horrible. Last couple have been much better. Was an awesome series till the middle, one of my faves.
"The Primal Hunter" Zorgath
A twist on the "world gets sucked into the system" trope. Nice writing, interesting world building, needs a lot of editing, but would be great if it had that. If you can ignore the problems, it's a great series.
I'll look back and see which series I enjoyed and mention them when I can remember reading them. The above were off the top of my head.
If somebody asked me to make a list of three LitRPG series those are the three I would list. They are the three I still read weekly. All three of these suffer from the same problem, the author has created a world where it takes 'millions of years' to hit max rank but they are following the character day to day so they've written 900 chapters over five years and the character is still rank 3 out of 10 or whatever. The series just go on and on and on and on with no real interest in a narrative conclusion. I still like them because the point is the progression but it does eventually start to wear on you.
I agree the middle books of HWFM were miserable. The entire Earth arc was a disaster. I get what he is trying to do with the mental health thing but it was extremely ham fisted and repetitive. They get better once things lighten up again.
A couple decent series that are noteworthy because they actually have an ending: Defiance of the Fall by Tao Wong and Cradle by Will Wight. Both series have their ups and downs (the first two books of Cradle are pretty mediocre) but it is nice to actually have an ending. They are also more progression fantasy than LitRPG. DotF is sort of a hybrid with light LitRPG.
My favorite prog fantasy is The Weirkey Chronicles by Sarah Lin. That one is a fairly new series but it is one of the few where I eagerly anticipate the new books. Arcane Ascension by Andrew Rowe can be a little cringe and has ups and downs but it is extremely popular and I like it well enough. The Completionist Chronicles by Dakota Krout has a strong start and an uneven middle, they are good enough I will keep reading them.
It is very common in the genre for authors to plan out a 50 book series and get bored after 7 so you sort of have to be OK with things that peter out and go nowhere.
