Best LitRPG
Format: Kindle
This is absolutely the best litRPG I've ever read as well as the best self-published series. Between the character progression, the amazing sense of humor, and the relatability of the characters, this is my top recommendation for anyone interested in litRPGs. I fell in love so much that I had to sign up for the Patreon account so I could get my fix regularly (5 new chapters each week). I even managed to get my roommate hooked on the audiobooks.
If you're looking for a fun story with loveable characters, surprising insights, and epic fights, this is for you.

What the??!!!!??
Format: Kindle
This book"kills" it!!! It kept making me laugh out loud and waking up my wife... NOT COOL!! She needs her sleep...and I can't really tell her what is so darn funny because She Hasn't read any of this series and wont get the joke. It also brought tears to my eyes reminding me of actual life events I've lived through. Loss,honor, loyalty, friendship, dangerous situations... Amazing stuff! I can't stop laughing and reading. Awesome...

A lot of useless skipping around...
Format: Kindle
So, I really enjoy the underlying story, but I really wish the writing was cleaned up. There were so many little sections, a few paragraphs to a few pages that were bouncing all over the place. And while some sort of moved the plot along, the vast majority were just filler.
It would have been significantly more fluid if events were portrayed through characters experiences, than just having narration about everything happening all over.
In addition, I know this is a web novel, and they tend to be written chapter by chapter. This, painfully, results in less cohesion from start to middle to end. The story ends up feeling choppy, and the overall arc throughout the book suffers. In fact, over >700 pages and we really didn't make a ton of headway until ~60% of the way through the book. That's when things really started. The majority before was fluff and filler. Useful, but only once distilled and refined.
I'm really hoping that for future books, Shirtaloon spends some time really thinking what is critical for the plot, and how to incorporate as much of that plot progression through the lenses of the characters in lieu of just narrating pages and pages of stuff. For example, instead of spending 100s of pages on mentioning all the places in the world crumbling from infighting and corruption, instead portray that through the character. It reads so much better, and ends up being more concise, and allows for opportunities for further character development all while building the world.
I love more story, but I'd prefer reading a 700 page story. Not a 400 page story in 700 pages. Let's make all the pages matter.

Another Good One in the Bag
Format: Kindle
Love the change this adventure keeps taking. We go from our LitFantasy to a comic book adventure. One of the most interesting LIT tales I have read so far. The adventure continues to hold you captured and throws in a few twist. Didn’t see those 3 making an appearance in the Reapers Realm. But, no other spoilers, just read it; it’s definitely worth reading!!!
Cheers 🍻
Peace ✌🏾 & Love ❤️
