This manga is ridiculously childish and the same goes for the novel. It's also not amusing at all. It insults games and gamers alike, not to mention that it insults your intelligence with half-baked knowledge and world building/story. A score of 8/10? It's barely worth 5/10.
The thing that makes this so bad is that it underestimates games, gamers and makes stuff utterly and completely illogical all the time. The stupid jokes that just doesn't work because it's more annoying than funny doesn't help.
Let's mention a few things. First of all, NO one seems to have chosen crafting professions because it's "unnecessary". I call utter bullsh*t on that one, especially in a VR game but no matter what game it is, some people like to do that stuff and they're not that rare, that it's not that beneficial doesn't matter, it never does. Normally it has to do with achievements and doing stuff, but in a VR game it would just be funny nonetheless.
Then there's skills. The very idea that some skills would be completely useless is stupid, especially things related to weapon use, just how f*cking bad is the programmers if they can't even somewhat balance things? A profession or skill is NEVER useless, be it real life or a game, everything that matters is how skilled you are at it -.-
Oh, the mc plays around 2 hours a day and manages to keep up with anyone and everyone. He's also not serious at all and never trains, yet he somehow owns the more hardcore gamers, even PvPers are trash in front of him for some reason, having inferior gear and skill doesn't matter because he's so f*cking awesome despite the fact that he should be useless. Just how stupid does the author think we are?
When cooking, for some reason he gets "kidnapped" by people because they want to taste his dishes. So, what does he do? Yeah, every time he logs in, he's "forced" to cook for people while he actually wants to go elsewhere and play the game, but no, for some reason he can't imagine the idea of saying "no!" or just walking away, he just complains and cries. I think anyone would get the message that he's not going to cook for them, there's also no pressure in an online game, who would even hate him for it? Unless they're retarded, they would understand that it's nothing wrong with wanting to do other things with your time. By the way, they don't mind waiting for very long times just to get some slightly tasty boost food, who'd even waste so much time standing in line when you can do funnier things inside a game?
Then there's the part where suddenly, there's a message from an unknown adventurer to everyone and all potions etc disappear from shops because people shouldn't get comfortable and they want people to appreciate crafting professions! So, suddenly the mc is pretty much the most popular guy around and just spends all of his time crafting crap for everyone, because he's pretty much the only crafter around. What are the possibilities of something like that happening? Absolutely zero. There's no way things would just disappear from shops without any forewarning, or at all. There are other ways to make crafters useful enough to make it a viable profession. But, no, like everything else, just f*ck logic.
Just how badly does the author want to make the mc into a godlike existence? If he wanted that, he should've played by the rules, made the mc play games at least 8 hours a day and he should've put in a lot of effort to get good at everything. He shouldn't have made the mc into an "ordinary middle aged guy" that doesn't have the motivation to do anything much with supposedly crappy skills. He should've played within the boundaries of what is possible in a game world.
You can't just say that "it's fine because it's a game!". Nope, it's not. Even games work around certain rules and regulations because they'd be shitty games that just doesn't work otherwise. There are things that has to be true for a game to be a proper game. Some things are impossible no matter how much you stretch your imagination and this manga/novel is full of that kind of crap to the bursting limit. Even fantasy worlds need rules/laws and some things can't be changed without turning the entire thing into crap that not only insults itself but also insults us, the readers. It needs to be somewhat realistic, somewhat possible and logically sound. But all too often do I find that some authors just doesn't understand something so fundamental. Why are they even authors in the first place since they clearly aren't good at it?
Honestly, I mainly cringed and even got irritated by the extreme logical fallacies present in this garbage manga. How can I laugh at it when it's just moronic and stupid? Things are usually funny because the things they do are POSSIBLE although unlikely, preferably it should also be RELATABLE. But this has none of those qualities.
Maybe someone who've never been a gamer before and doesn't understand how absurd and idiotic it is would like this far more.
