Webcomic Has Some Pretty Glaring Flaws
As someone who grew up playing video-games, a series titled The Gamer was practically calling out to me. Sure enough, I was caught up in the hype, because the first 40 or so chapters is just loaded with gaming references from level grinding, skill/item gathering, and such that I was sure this was going to be an incredible series. However, as that initial hype wore down, I started seeing the major issues that plague this series. I still enjoy keeping up with the recent chapters, but these problems are quite clear.
1) The pacing is slow. Like really, REALLY slow. As much as I liked those first 40 chapters, it, for the most part, was nothing but level grinding, and world-building explanations. Afterwards, the pacing is hit with a different problem, which gets to...
2) There's way too much exposition. So much so, that you'll eventually start feeling like you're in History 101 learning about Korea's backstory. And like the first example, there's way too much world-building exposition thrown at ya throughout the series. As a result, it takes forever to actually get places.
3) The fight sequences are incredibly lackluster. For a series that basically follows around a guy with the powers of a RPG character, you'd think that the illustrations surrounding the combat would be one of the things the makers would get right... Get ready to watch the main character spam Infinite Spinning Mana Arrows later on, because it becomes quite apparent as time goes on that the people who make the Gamer don't know how to illustrate creative and intense battles.
Webcomic Plain Terrible
Finally dropped the series after reading hundreds of chapters. Some issues that I would consider to be its most glaring flaws:
1. The plot.
It's often dragged on for too long, way too many expo speak (watch out whenever the protag is explaining a yet new mechanic of his power or anytime someone is talking about the history of Korea), awkward pacing in general, and at times seem to be written by the seat of the author's pants. There's also the power creep aspect, which is terrible even in comparison to most action series.
2. The characters.
The protagonist can be charitably described as a bland gary stu, whose only personality seems to be how strong he is thanks to his hilariously broken ability and how much he wants to be stronger. His friends are slightly better, though even they still felt more like living props for the protag at times. The villains are even more terrible. None of them I can consider to be interesting, be it their ability or personality. The Company is especially bad at this.
3. The art.
It's mediocre, at best. Many of the characters appear to be copy pasted on with little differences being in hairstyle and colour, the backgrounds are very basic looking, the paneling is awkward. Lastly, the very stiff fight scenes. The last one hurt especially bad for an action series.
4. Other
Even the "video game" part of the manhwa, the supposed main attraction of the series falls flat. Anyone who had played any RPGs could probably tell that Protagonist's power doesn't make any lick of sense. Ridiculous and inconsistent growth, Absolutely broken mechanics for no reason other than MC's convenience, and so on. If anyone tries to emulate the series system in a real RPG they would run into real serious balance issues very early on.
Tl;dr: No strong point except for the wish-fulfillment aspect.
