Obviously, the OG, the GOAT.

It's similar in the world-building and leveling up system thingy. MC is riding a train and reading the final chapter of his 5000 chapter long novel series and gets transported into it. Now he has to stop the novel's MC from regressing and trying to survive with his cheat abilities. ... more>>

-has a manhwa/webtoon! (same name) <<less

The main character sort of reminds me of Jin-woo, it's mainly his attitude. I think it's just the vibe in general. The MC gets isekai'd into a novel he's reading as the tr*sh of the counts family (ofc) and the tr*sh dies early on in the series, so he decides to steal almost all of the divine relics so he can SURVIVEE.... more>>

This one is similar in the way the main character gets a set of (not really) new abilities. It also has a funny and interesting main character, and in the way the world is built with the leveling system, ranking system, and dungeons. The MC is an F-rank and has a younger brother that is an S-Rank and has hated the MC ever since he became an F-Rank. But it turns out that the lil bro is a bro-con and died for our MC. He gave the MC an artifact that can make almost any wish come true, so MC wishes to turn back time. ... more>>

-Has a manhwa (same name)  <<less

This one is just for those who like romance and isekai. Main girl is an S-Class Hunter and dies and gets reincarnated as a princess who's a villainess in a novel. She tries to get out of the novel and finish her "mission" she was meant to complete in her previous life. ... more>>

-Has a promo manhwa. <<less

The main character used to be tr*sh, like, tr*sh tr*sh. But then, he gets (technically) coaxed into going into an alternate world where he gets spawn-killed, but he goes back in time and fixes things up with his life, both in the real world and the alternate one. The main character's attitude kind of reminds me of Jin-woo because he actually tries to get better lmao. (kinda confusing for me tho)... more>>

-Has a webtoon (same name) <<less

Main character has a missing brother and after like, 5 years, he finds his brother's pocket watch and sees his brother's diary that states that he's already dead by the time MC will read his diary and that he died from climbing the Tower of the Sun God. The MC then goes to climb the tower to avenge his dead brother. I think the MC is similar to Jin-woo and has a similar world with the ranking systems and fighting monsters.... more>>

-Has a manhwa with the same name <<less

MC is similar to Jin-woo in my opinion. He used to be a pro-gamer for this team and got kicked out because he was "old" (it was actually because he got replaced by some rich kid). The MC is now poor and goes into a PC cafe to play some games for the last time. There, he meets the female lead (i think) and shows her his pro-gaming skills and that he is actually the gaming god (metaphorically, not literally lol).... more>>

-It has a donghua (chinese anime)! <<less

This has that same game-like system and leveling and stuff. The MC is a construction worker both in reality and in the VR game "Satisfy." He, one day, finds a cave for a quest and finds a legendary book and he, himself, would become legendary. ... more>>

-About 1,000+ chapters and has a manhwa with the same name (80+ chapters). <<less

Like the title states, it's about dungeons and I think that's pretty similar in itself, but it's about how the MC accidentally survives a dungeon, meets a crazy bunny (in the cover art), and is literally a glitch in the matrix. The dungeon(s) he's stuck in always resets itself since dungeons reset after users activate all of it's traps and stuff, but MC is a glitch and doesn't really count as a "user." So he tries to meet actual people and go back to the real world.... more>>

-Has a manwha with the same name (about 55+ chapters). <<less

MC came back to Earth after being isekai'd for 20 years and sees that Earth isn't the same anymore. All his stats are back to zero and now he works to becoming the world's STRONGEST NECROMANCERRRR.... more>>

-has a manwha with around 30 chapters  <<less

How could I not add this one? The main character is bold and smart like Jin-woo and has the same world-building as Solo Leveling with the game-like system and set of new (OP) abilities. It's about how the MC wants to become an S-rank hunter and finally has the chance, except he has to die. lmao... more>>

-Has a manhwa with the same name (about 60+ chapters). <<less

This one has dungeons and MC has OP abilities like SJW. The MC gets isekai'd into the novel that he wrote. He thought that going back home would work, but it seems like, the novel is different from what he wrote. ... more>>

-Has a manhwa with the same name.  <<less

This one also has those dungeons and hunters things, except in this one the MC is a manager for these hunters (kinda like how an idol would have a manager that manages their schedule and stuff). I haven't actually read this one so the desc might not be good but uh yeah. Anyways, the MC retired from his previous job as a Hunter and instead wants to become a manager for these hunters. The author hasn't told us why he retired yet but he might've been in an accident that caused him to find a new career in life. I heard the MC isn't really OP tho so if you don't like not-really OP MC's,... more>> then idk about this one lol.

-Has a manhwa with the same name, or the name "The Mightiest Manager." 

-I also heard that the manhwa is better than the novel so yeah. <<less
