Why did Craig Zerf bother putting his name on the front cover if most of it wasn’t even written by him?
I immediately noticed something was off about this book. Compared to the first entry in the series, the writing is bizarrely repetitive and flowery, almost like it’s been written by a kid who just found out what a thesaurus is. The majority of the descriptions and fight scenes were almost certainly generated using ChatGPT, as they feel lifeless and sound literally nothing like the author’s usual style.
Even if book 1 was quite juvenile, it was still incredibly fun — and most importantly, not written using AI. The very fast pace at which this series is being released makes it blatantly obvious the author has well and truly stopped caring about the quality of his books. Up until now, I really did enjoy his work despite its flaws. After this, I don’t think I’m going to read any of his newer releases.

Level up It's a LitRPG World is the second book in this series, and while this book could use some additional proofreading, for the most part, it's well done. My only beef with this one is the whole discussion on thunder bolts. I'd not care if the main character wasn't asked by his trainer if he knew what they were, but since it was brought up, I feel it's necessary to set the record straight on this.
The main character was asked, You do know what a thunder bolt is don't you, to which, he answered, of course I do. (obviously not). To be technically correct, there is no such thing as a thunderbolt. It's lightning that passes through the air, which is actually so hot, it basically turns the air to plasma, but because it's so hot, it expands the air in it's path so rapidly, that we get the sound of thunder (no apologies to Ray Bradburry fans). Therefore, since thunder is the result of lightning, it can't be a thunder bolt that makes the lightning, it's actually the other way 'round.
With that off my chest, I will point out there were multiple places in the text in this book where errors occured that should have been caught in proofreading. for example, when he ran 300 yards in as many seconds. That means it took him 5 minutes to run the length of 3 football fields. That is not possible since he was supposedly moving faster than an olympic runner. Even when I was in sixth grade, I ran the 50 yard dash in under 10 seconds, which would translate to less than a minute for 300 yards. If this guy is moving faster than an olympic runner, it would be way less than that for him. (I realize these are nit picks, but again, proofreading. In another spot, there was repeated text. Sloppy, but not critical.
Despite these irritants, the story was still a great story, and I'm not stopping the reading of this series, not by a long shot.
I'd expect most LitRPG fans to enjoy this one.

Some pages of this book- particularly a big battle near the start are clearly written with chat gpt AI or other AI program. You can tell by the way big vocabulary words are stuffed into the paragraphs with a lack of understanding on how to fit them in a sentence. The grammar at isn’t actually wrong but rather so regurgitated and typical that no human writer would write multiple hack paragraphs like that.

I am doubtful the writer will respond as it is just so obvious if you read it that parts are written by an AI program. I doubt I will finish the series the first book was mildly entertaining but I don’t want to read very bad prose with smart sounding vocabulary word salad. And in case people want to know how I know- let’s just say a lot of experience with writing and AI….

Just read some reviews someone else clearly saw it was AI written too- I revised down to 1 star

Diggin this series

I really enjoyed this. The story progression is fun and I like how his “disciples” give him a hard time constantly.

Gave it 4 stars because a couple things bugged me. Very little character progression. A few spells randomly get unlocked and a class change.

Also, a lot of things are explained or skipped over in what came off as a lazy way. No technology because it got switched for the medieval equivalent. Why though? They were supposed to find this amazing lost city to uncover legendary loot and rewards. Nope just some rather boring loot that was barely magical. Lots of things like this.

It wasn’t enough to ruin the story, but enough to take the enjoyment down a notch for me.

ok but not special, liked the 1st book more

The MC leaves the training dungeon and goes out to find that 4 worlds have merged with earth by the system. He picks up a handful of disciples as he wanders, slaying individual and bands of monsters. They also assist a few enclaves of elves, humans and faries. The writing is decent and the background descriptions of the environment is very good. However the characters have little depth, there is minimal relationship development and no love interest at all. The storyline didn’t do much for me until the last chapter where the MC received a new quest.

So much potential

Great story, fun characters and lots of potential. Characters need way more development though. And the system makes zero sense and keeps pulling me out of the story. I try to take it for simple entertainment, but the holes kind of ruin it for me. So, to the author, please rethink your experience and system dynamics. They make zero sense. A level 68 killing a bunch of level 10s should not get 7 levels worth of experience. Level 11-12s fighting level 50-60?? Mobs that hurt the main character at level 60something? Might as well not have levels or experience. Otherwise, it’s a fun read.

Survival of the Human Race/ Leo's Quest

Leo is just a guy looking out for the next guy, but he's also been trained exceptionally well. He is a fighter and now magic user, thanks to the 'system'.
90 percent of the human race has been wiped out when the system combined 3 worlds together. Leo just wants to find more humans to help, but the system is screwing with him to do more...
The battles are fun and his continuing growth of disciples, forced on him by the system, give him more to worry about.

Fun read! Read in 2 days

MC is lowkey pathetic

For the fact that the MC is over 5 times the level and approximately 10-15 times the strength of the other characters on paper due to power scaling, he relies extremely heavily on those weak supporter characters. His attitude is also quite offsetting and seems to live life with the flow, not really actively doing anything for his own betterment. Overall quite the disappointing book especially since he is a hunter, an archer who rarely uses the bow.

needs proofing

Good book. Book one was very good but book two the story seemed rushed and the story mechanics don’t make sense. I ran into a whole lot of errors and marked them. If others do the same it will make it easier for author to re-edit. Overall looking forward to third book.

Very good

This book was a lot of fun. If you liked the first one, you'll probably like this one too.

It is a tad short, but that makes it perfect for a quick evening read.

Highly recommended.

Exciting series

Interesting post apocalypse novel. Main character is a bit random and the language is fairly ripe. Also quite a few typos. In spite of this I enjoyed it and will definitely get the next book

Totally different than first one

The first book made the mc a loner and someone I could like, the second turned him into a "hero" someone I could not stand at all!! The only hero you here about are dead, so why should I read something that I hate?

Dumb and Dumber graduated college…lol

Well Book 1 was a cluster but Book 2 has redeemed my confidence in this author and RPG books in general. The main character has managed to graduate from being a complete idiot to being a half way decent leading hero. Wow, what a change in a book series. Let’s see what number 3 is like.
