This is not a story about a guy trapped in a game world.

Well, it is I suppose it is. But thats not the point.

What it’s really about is New Communicate Online, the buggiest, most sadistic singleplayer VRMMO known to man. Come, marvel at the legend of the Master Torch and its Underground Dojo. Learn why repeatedly slamming your head into a wall at breakneck speeds is the true path to power. Weep at the tragic fate of the Armor Knights of the Cave of Trials. And fall in love with... more>> the greatest, most lovingly modelled cat ears in all of gaming.

Basically, its a glitch speedrun in novel form. And its amazing.

The non-glitch related parts are quite good, too, which doesn’t hurt. <<less

A comedic spin on transported to game world fad. The novel satirizes the illogical nature of games, and the fact a game would never work as a real world due to the limitations of games. The main character is brought into a fantasy world that highly resembles a game that he is addicted to. The game was created by heavily flawed developers that loved to abuse their customers, and focused heavily on their fetishes while ignoring glaring bugs in the game. Its funny.

I don't reccomend picking it up, its... more>> being translated far too slowly. I hope the translator would drop the novel so someone else could actually pick it up and give it a decent job. Its taken three years to not even translate two volumes, at this rate we are looking to spend fifteen years to wait for the whole thing to be fully translated. <<less

Things I like about the series:

While the setting overall is fairly standard (MC transported into a game world), the execution on this concept is great. The MC is in some ways OP, since he has a complete understanding of the world mechanics while those living in the world do not. However, the author does a spectacular job keeping the tension of the world high by making the setting a place filled with a multitude of ludicrous bugs, odd quests, and exploits. My summary of the setting doesn’t do it justice.... more>> Each new situation is made interesting, especially as the MC’s actions are pretty silly to a common person, since he is abusing bugs and exploits. The contrast between the MC’s thoughts, the game-world character’s thoughts, and the background information on the prior game world really does make for an interesting read.

The NPC (s) (which is so far mostly the first heroine) also so far well written. They have distinctive traits left over from the game world to start, but as time goes on, the character is getting fleshed out more and more as the story progresses.

Things I don’t like about this series:

So far, I haven’t run into any complaints (at the time of the writing of this review, up to V1c5 was released).

Overall Evaluation:

Read this. Especially if you have interest in reincarnation / gameworld stories, or just interest in humorous stories overall. <<less

The description made me skeptical as hell. Oh, a buggy game and our main character is there. You're just trying to say this guy is a cheat aren't you?!

I was wrong, I am glad I was wrong. It's hard to explain the charm of the novel, but it's straight up a sh*t game. The main character gets transported, and you go through this super veteran attempt to play through in a completely unreasonable game.

The side characters are well developed and cute as f*ck, the main character is interesting, the broken-as-f*ck... more>> setting is lovingly crafted. Even if you don't normally like VRMMO/Transmigrated to video game world settings

I would still recommend this.

Seriously, give it a shot. <<less

I really like this novel as it's very realistic to how players would play a game.

It's very rare to find a concept of a broken game where bugs are abused, and Nekomimineko is a game with a community around it that despairs, laughs, and celebrates the good and bad in the MMORPG world.

Filled with gags and with some nice improvements over characterization, Kono Sekai Ga game is worth reading

This is really good, really enjoyable read.


-Unique setting of MC exploiting the game (now real) world's bugs and knowledge of future events, in order to become powerful

... more>> -However, he still has to work hard to win his fights (most of them, lol)

-Lots of humor; after all the game world was created by a crappy developer that furthermore likes to make life difficult for its players

-Very well fleshed out world, especially describing the changes when game world and NPCs become real people

-Supported by well developed relationships with side characters/heroines


-Can't think of much; maybe lack of introspective moments for the MC as the plot doesn't stop moving? This is more of a nitpick though considering this is a comedic story. Anyway, there's enough serious bits to make the characters feel real. <<less

I really didn't manage to get into this story at all.

It's not that the story is terrible, or that the writing or translation would make it unreadable, it's fine on those points.

It's just that the flow, the descriptions and explanations, everything is just "this world is a game I already know".

... more>> The premise might sound interesting, but sadly the author forgot to make the NPCs into proper living beings, so the whole world feels dead from the very start, and we are left a story that's not really that catching.

It might have worked if the author had made us discover the quests and bugs along with the story, but we are introduced with quite a lot of the "bugs" and "quests" right from the start, without the character actually encountering most of it, making all of it even more artificial.

That said, as the writing isn't that bad, and the translation correct, it's ok to give it a go. Just remember, each "chapter" is really long, so don't think "meh, parts for each chapter, lazy translator". <<less

This novel is good. And considering the great majority of Japanese webnovels, that puts this novel on the 99th percentile.

There's nothing complicated to say here. It's simply entertaining to read. That's it. You want a decent Japanese novel for a quick read, something that's.... I don't know, not s*upid?

Well here you are. Start reading.

It's real good. Funny too.

I couldn't wait for the Light novel translations and read a really crummy Google Translate of the original web novel. Regardless of the gross quality, I still managed to pull out the gist of the events that happen. I'm nothing more than hyped for the reveal of, and return of, various characters. Anyways, onto the review!

It's a rather unique spin on the typical "isekai/game-world" trope, since the game-world our unfortunate protagonist, Souma, gets stuck in just so happens to be the world's buggiest VR game created,... more>> New Communication Online, which so happens to be a single player game... because the development team found creating a VRMMO to be too much of a hassle.

On the bright side, our protagonist knows basically everything there is to know about the game. The reason he got sent to this game-like-world in the first place was because of his addiction to it. While Souma provides various explanations of how skills work, and why some bugs exist, I found it incredibly entertaining to read. Rather, I was always thirsting to find out more about the world known as Nekomimineko, and the characters and "features" that inhabit it.

If it wasn't obvious enough. This is a comedy. The author will subvert what appeals to be "dramatic" into something comedic, basically making everything feel rather anticlimactic. I will say, this process is repeated quite a few times, even in the web novel. Despite this "rinse and repeat, " I still find much entertainment from it, even if I started thinking to myself, "what kind of bug will he exploit now?" There will be some genuinely "dramatic" moments without subversion, but those rarely appear. I think this has only occurred probably twice in the course of the web novel.

In conclusion, I find this to be a "Konosuba" of the Trapped-in-a-Game genre. The world is incredibly strange, and character interactions within that world make it funny. <<less

The synopsis and initial setting are generic. However, the skills of the author allowed for a fun adventure. By reading the story, I believe that the author has had experience with RPGs before. The author describes in detail: the effects/bugs of skills, the consequences of said skills, the bad end of events, the player-abused exploits, and, most importantly, the perspective/reaction/actions of the general NekomimiNeko populous. The author stays true to the rules/boundaries that he set out even though he has used the fact that 'the world is no longer a... more>> game' to squirm his way around certain limitations like pre-programmed lines and invisible walls. He's also an adept user of the concept known as Chekhov's gun.

The audience that would best enjoy this story would be RPG players (Divinity: Original Sin 2) that enjoy the hilarity of watching videos of people messing around with bugs. This novel is similar in that the audience is reading about the hijinks that occur to our MC within this buggy world.

One doubt that I've had in my mind is about the shitty events. It has been described that there are many unsuspecting events in which if completed, the story becomes insane if not completely impossible to complete. However, while such broken events have been described in high detail, such GG events have not happened to the MC yet (though he has encountered his share of headache-inducing events). However, if I think about it from a narrative standpoint, once such an event occurs, then this story will basically end right there. Thus, I've come to rationalize that once the MC detects the possibility of such an event in the horizon, he'll do everything in his power to skirt around the event instead of overcoming it (which is fine by me). He's used such a principle when dealing with psychotic, narcissistic, or just crazy NPCs.

All in all, what I've read is great and I have faith in the author that the story will continue to be great.

P.S. I had a great time when I imagine this game as a trolly D&D campaign. <<less

It's a masterpiece of a novel, out of all novels I've read this was the most entertaining to read, it doesn't have any drama or gloominess, just pure thrill, comedy, and excitement.

I genuinely recommend reading this.

If your hesitant on reading this I would recommend reading the manga just to get a taste of this.
