I have only read the first 6 volumes. I'm lazy to articulate and I honestly think this form is very clear:
The protagonist is fine, a good character, but all the others are way too dumb.
Worldbuilding is just great.
The fact that administrative capabilities and political action are given enough space, not pushed too much aside by combat, is very good.
The battles are the most awful display of absolute ignorance, with the author literally explaining the mobile games' scheme lance>cavalry>sword>lance as military strategy.
The misconceptions about European Middle Ages are abundant.
The author continuously interrupts the narration to start showering his own MC with compliments, repeat his previous words and wander off with general considerations about human nature. This happens especially in the 6th volume and ruins the pace.
The plot is complex and rich, although some secondary plotlines are left lying down for too long.

Overall I like it enough to be eagerly waiting next chapter, but I wish the author could actually write and he clearly doesn't, which is a pity given the potential.

Edit: Apparently the author just switched to the LN format (the story continues from vol 19 more or less)

Edit: cant really recommend the LN... It just drags out everything plus, even though the author does fact check the Japanese part on the volume 19 he did too many mistakes/underestimates too much a constantly waring civilisation.They stop and hesitate on an empty city instead or reoccupying it with the refugies and pulling the loot to a square or the main camp ... just to have the dullest defeat ever. There were also many logistic reasoning done wrong (soldiers consume way more food than normal population, locals would obviously know the city better). I mean wow what could you do against a wood fortification in a place without water, lets suicide all out troops against it how could we possibly think on burning it or ignoring everything attacking by sea (it's a peninsula full of monsters with only one costal city).

It's really action packed mixed with lots of intrigue. I read up to vol 7(WN) and so far it's really entertaining since it mostly doesn't tell you all of the MC's thoughts and we get to see his crazy ideas/plots unfold (from both his perspective and the ¿enemies?).

What I most liked is how the MC isn't the only person that thinks there are various factions with their own objectives and dynamic ways (they also change their plans ,spy on one another ...). The MC is actually riding on another one's plan knowingly or not.

I also found it it quite didactic how the author sometimes gives Japanese historic details instead of randomly blabbering of how great "xxx" historical figure was without saying what he did.

Saying the series is perfect would be a lie but you can easily avoid chapters you don't like .I read it all ,but it you could be easy to skip some 1 on 1 battles and just keep reading where the other dies or for example it vol.6 skipping all the court stuff..

As most light novels out there this one has it's pros and cons
From a narrative point of view, the author describes things and sets the foundations to events making it a very coherent and consequential story, this brings some pacing issues at times and it can also be redundant with the explanations and Ryouma's monologues (a problem too common in web novels unfortunately). It's also quite mature, for example, slavery is taken very seriously and brutally depicted. War is likewise way more deep than most novels I've read and I'm not qualified to judge on how accurate it is but the strategies, action and counter-action and conditions of each battle are both well explained and executed. It also doesn't go (so far) on the harem route, the two females are also mature and don't frown on him nor impose themselves on him, not to mention that for a change it makes sense that they would want to throw their luck and bet on him for their future (for those who come from the manga, the girls here are not pushy nor needy nor interfere in Ryouma's life when he for example goes to a pub and sleeps with the waitress). Which brings to the next point, Ryouma treats women as women, he's not the classic idiotic virgin that gets a nose bleed when a girl talks to him and has 10 beauties asking him to have sex with him and he is either oblivious or too shy about it, Ryouma for a change he has relations with some women and in an adult fashion.
Yet for all the attention to detail, is at times inconsistent, for example, summons are random and from earth as a hole yet each and every summoned person is Japanese, if the author was going to do that then was it not better to just restrict the summons to Japan? That would also solve the language issue, otherwise all earthlings just speak and more importantly read the isekai language which needless to say, can not be the same as all languages on earth. Also some characters act are presented in one way but later in the story act completely out of character, I won't get into it to avoid spoilers. Same goes for the story, the author seems to be loosing interest or steam as he progresses and the logic and consistency ain't as sound after volume 4. And as the guy below, Jandalman says, the output of the author is slow, very slow, I don't know why he says they are were in the second arc since at that point the story was already in it's current volume/arc, the 6th, regardless, there is with luck one chapter per month and I'm not talking about the translation but the official JP release. For the translation, search Wortenia + Hatsutsuki in google and you'll find the releases, they are at v6 ch23 right now (WN). Also, if you wait 3 years to read the story it means you are interested, voting a 1 seems a bit childish...

As for the story, there ain't much to tell, MC goes to an isekai, he's been trained by his grampa to kill or be killed so when he's about to be made a slave he strikes preemptively and kills the summoners. There is a leap of faith that need to be made to accept this at face value but all fantasy stories demand such leap, that the author made it at the start and is thus a defining quality of the character makes it an easy one to accept for me, others will disagree. MC then tries to forge his life in this world and without spoiling much, he gets a purpose after finding the treatment his fellow summoned (Earthlings?) suffer and gets a fiefdom. Simple but well presented.

Overall, I like this one quite a bit if you haven't noticed, it's a good story, presented in a solid and consistent way (which I value highly), with real characters and a believable world. The bad, imo, is the pace and the aforementioned lose of steam on the part of the author which introduced some inconsistencies and "not so mature" aspects later on. I'm waiting for volume 6 to end to read it in one go, I hope it gets on track in it but it might as well get worse.

Sorry for the length

This novel is an absolute shitfest in terms of pacing and character designs. I have literally put the novel on hold for YEARS due to it's slow pacing only to finally check on it today to see that the MC is still stuck in the second arc of the story. He has literally been stuck (thanks to the retarded author) dealing with the same shit from the same douchebaggy people since I last read in 2016! Everything to do with this series is a heaping, steaming, rancid, festering, titanic-in-proportion mountain of shit and I wish there was an amnesiac pill I could take to forget I ever gave this filth a chance all those years ago.
