(I'm only making two comparisons to RL since their honestly the only things that I deem similar between the two works)
Madness Apostal caters to the small number of readers who are interested in stories revolving around real Villains, someone who's goals and interests take precedence over familial bonds, morality and just about every 'normal' human relationship. The world and power system are intricate and expansive, I actually doubt the Author will have the opportunity to explore every nuance and attribute introduced in the series in-depth but the job he's done so far could probably fuel quite a few fan-fictions if that's any 'real' indication of how interesting and large the world gets later down the line but in my honest opinion I find it much easier to understand and interesting than the power system of Reverend Insanity since comparisons will be made.
Arthur Kovacs is compared constantly to Fang Yuan of Reverend Insanity and from first viewing it's simple to see why. Their both ruthless individuals who only have their personal benefits in mind when taking action, their both unperturbed by the required blood and gore needed to accomplish a task, and they both have lived lives completely beyond the comprehension of anyone they interact with. Giving them a baring and personal quality that can't quite be captured in a single explanation. Unfortunately quite a few people stop their comparisons there and ignore the fact that Arthur has lived longer than Fang Yuan. This in itself isn't that big of a detail but it separates the two by an invariable film, Arthur is more direct in his actions as opposed to Fang Yuan's cunning, he despises those who have potential yet waste it, while Fang Yuan simply doesn't believe that innate potential is the be all end all of a person's existence. They both refuse to give up as long as their hearts still beat and their synapses continue to fire, but gamble with their lives if they believe the rewards are worthy. Both very compelling people, but Arthur at his core is inquisitive, daring and confident while relatively Fang Yuan is greedy, careful and prefers to keep everything about himself close to his chest. This comes down to the fundamental principles that govern their worlds and cultures along with their personal experiences, Arthur growing into a Demon having suffered loss after loss and realizing he's but a frog in a well obsessed with understanding the greatest powers in the world while Fang Yuan has always been weak and unable to fulfil most of his goals but remained an individual dedicated to his personal betterment, he too becoming obsessed, yet with the notion of his existence becoming eternal.
Gu Master's can basically accomplish anything with the correct resources, luck and attainment level while Fae Master's must hone their respective fields and understanding of the world and themselves to best execute their true abilities(their comprehensions only adding another layer to their arsenal instead of being the foundation that blooms into their overall combat strength).
Other characters are compelling in their own right. The Kovacs clan is comprised of tens of individuals with their own aspirations, schemes and personal baggage that allows us as readers to really delve into the minds of these individuals who must fight and train themselves near constantly to be relevant in a strange complex world that constantly changes and becomes more dangerous to them day by day. Personal stagnation is a death sentence in this world and the Author isn't afraid to show that.
Visually I'd say the scenes and characters are depicted decently, with enough descriptions to paint a wildly colorful and exquisite world. Characters are also depicted quite well with just enough attention given to detail to make them discernable even with the time between releases.
The politics, rationing of resources, psychology and rationalizations of characters are explained flawlessly. Everything working in tandem to give this world a true beating heart to enrapture any reader looking for something interesting and unqiue, what with all the regurgitate sub-par works overflowing on the app. If you've come across this novel and are unsure if it's for you I highly suggest reading the first 40 or so chapters before making a definitive decision(not many can stomach what happens beyond).
