This novel is one of the best original novels on here, don't get throw of by jacks arrogance at the beginning since he has a good reason for it, if you haven't started reading it, do it now. The novel's at it's last arc so you won't have to wait for the story once you caught up since it'll be finished then. Enjoy.

Good read. Long but worth it. The characters are well written, with very little to no plot armor. Characters have flaws which is important, as flawless characters are boring. Can’t wait to read more of your work in the shared universe.

The SEQUEL is out now!! "Outclassing the Achievement Junkie"!!! Join the new adventure following one of Jack's latest schemes involving a fresh achievement junkie MC, including a prologue with Jack and Bowzer in a dungeon crawl. Check it out if you want a fresh take on the Achievement System, new worlds to explore, tons of gods to meet/fight, and more AJ vibes than ever! ;)

Bad mc attitude. Very arrogant King: “Can you really help us?” Tries to clarify if the legends are true and if he’s really worth it. Mc: “Wtf man, I just need all this stuff and I’ll solve your problems ok?” Doesn’t provide any info at all and leaves once the king showed hesitation.

Just read chapter 2 and it is like the author had decided to put the most dumb and stupid things an mc can do in an isekai novel into 1 person. First of all openly declaring that he is not going to an ally would usually mean voluntary giving up your life because they have spent a lot of resources to summon you and the first you do is say that you're not an ally, if this isn't dumb than I don't know what is smart. Than even before the king can finish speaking he interrupts the king and in a disrespectful way says who are you and why am I here? Any culture on earth that has kings, future or present, has lesse mayeste rules to define what happens when someone is disrespectful to the throne and this mc just acts like it is normal to be direct and disrespectful while what is normal is that he would have been beheaded for his behavior. If this novel is full of these kind of illogical inconsistencies than I will quit reading this novel very quickly

After writing 600+ chapters, I'm writing a second and final review. By then, the characters and readers understand that Achievement Junkie is simply one world within a multiverse. Yes, I said MULTIVERSE. All stories that I write will be from different worlds in different parts of the audience-dubbed "Quillverse". Some characters and intergalactic knowledge may be hinted at or shared within the many stories, but each world and plot is completely different from the others. So, if you like an unpredictable, ever-growing world and universe where characters across various stories will meet and "cross-over" to work together and/or face each other, then you're in the right place. And no, you won't technically need to read them in order. You'll be able to read the final culminating story that connects everything without reading any other stories. But you'll be missing out on many hints or call backs, as well the satisfaction of seeing all the other worlds' characters grow and join the intergalactic battle. At the moment, there are 6 stories guaranteed slots in the Quillverse, with 5 leading up to the giant, final journey to connect everything. I may add more stories to the list leading up to the finale story, but I'm not promising anything apart from the 6 stories that I've already outlined and plotted at the time of writing this review. Thank you for considering my story, and I hope you find the entertainment you're looking for. Have a high-five. ヘ( ^o^)ノ＼(^_^ )

A fun adventure that reaches the hearts of both video game and fantasy lovers. Following the story of Jack and his growth feels real yet fantastic, giving a unique vibe and read. There's comedy and emotion laced in every part of the story so that you can better understand the characters and the events taking place.

grammer is fine, but the story, its just another chuunibyou author writing his wet dreams without much thought of how social life really works

The grammar is perfect so you don't have to worry about loses brain cells. The world building and characters are also really good; the MC's connection to the world he gets put in and how its handled makes everything more interesting. Not only is the story good but the author pumps out chapters like crazy and that enthusiasm is pretty good for writing a story, as it can be pretty easy to lose motivation if something comes up.

Great story with a nice writing style as well as good language use, enjoying every bit of it. Highly recommended. Chapter lengths are good and flows well. Wishing all the best to the author and keep up the good work
