Omniscient Reader: One of the most popular manhwa/webtoon ever, MC's favorite novel comes to life and he uses his novel knowledge to navigate the new apocalypse-game world.
Jungle Juice: Can't remember much rn but there's a community of people who get powers from merging with bugs because of some weird chemical spray. Pretty good.
Viral Hit: Bit of a slow burn at the start but dweeb MC learns how to fight and starts a fighting YouTube channel where he beats up mostly bullies for money.
Killer Pietro: Korea is ran/influenced by a shadowy mafia-esque organization that maintains its power by adopting orphans and turning them into assassin spies. MC is one of the first in this project who contributed the most and he is the highest "disciple" Peter. The organization wants to kill him (he's now 60~) and he magically inhabits the body of his 18 year old self. Hard to explain, just read it.
Study Group: Similar to Viral Hit but more focused on a team and school gang territory dynamics.
Samadhi: MC gains superpowers after talking to his friend from basic training who has them.
Pick Me Up: MC plays this game where you climb a tower with random heroes (gacha game) and then finds himself as a rolled hero underneath someone else's game. He has to use his knowledge of the game to survive.
Mr. Baek: Another fighting one in the same vein as Viral Hit, Study Group and Killer Pietro. I haven't read much of it, admittedly, but it has a lot of chapters.
Lookism: The progenitor of all fighting manhwa (I think). The story is decent but only up to around the 200 chapter mark. The story's been going on for like a decade now and has almost 600 chapters.
All of these have either really good or decent art, are either completed or ongoing with many chapters, and some like Omniscient Reader are considered to be the best manhwa ever. Though I've read probably hundreds at this point and I could give more recommendations if anyone wants them.
