good

no romance + isekai w time travelling + greek mythology + game-type w tower as basis of difficulty

mc – cool headed, cold (sometimes), has a humor and is cute (not lying ) wait for the chapter where he talks to an "ahjussi", intelligent, handsome.

no female characters that are annoying. this is so good plus the artstyle, everything.

no romance (not sure) + bro-con + brother complex + comedy + monsters + AND THIS IS ABSOLUTELY NOT SHOUNEN AI.

mc is a hyung, funny, has an average looks. there'll be (monster) pets here.

overpowered mc + monster and dungeons + heroes

mc – is cool, handsome, overpowered obviously.

there's a LITTLE-LIKE ROMANCE (spoiler)

BETWEEN THE MC AND THE ONE THAT HE'S BEEN TALKING WITH IN HIS MIND (it's a girl), skinship, and yes her actions are quite annoying because she's portrayed so girly-like, she's strong, nonetheless.

!!! SAME AUTHOR OF ORV !!!
game-type world, tower, monsters + LITTLE ROMANCE (said by the someone in the comment section) + overpowered mc + TRAGEDY (there's no tag but i decided to put it here because in the first two chapters, man, the mc's group died)

mc - is an overpowered character, handsome, cool, and though he experienced the pain of having all of his loved ones die in front of him; he's still somewhat in the right mind (not lunatic/psychopathic)

i don't think i have to put anything here just reminding those that there's little romance.
[ S P O I L E R ! ! ! ]
i also did my research, and read ONLY the last chapter of the novel – though it wasn't stated clearly and it's like it has an open ending, many claimed that dokja died, which i HOPE that'll be changed by the illustrator/artist here and that, is just my wish.

op mc + tragedy + isekai + mc is a villain + action + LITTLE ROMANCE (the girls died lol. fulfilling moments)

lots of twist. it was awesome, too dramatic with the background stories of the ending life of heroes and the villains.
