3 episodes into Solo Levelling and looks like they haven't screwed up the adaptation (unlike Crunchyroll's webtoon attempt) and the rumours that Omniscient Reader may be getting an anime too, seems it's the new goldmine for source materials (as reference, Manga=Japanese, Manwha=Korean)

Thought it'd be something light plus it's good to know unlike Hollywood, Anime doesn't need constant reboots to make new media.

Starting with most likely to get an anime:

Mercenary enrollment/Teenage Mercenary: this one seems like an easy choice, popular, got great characters and lots of action scenes to work with.

Solo farming in the Tower: with success of campfire cooking and Isekai Nonbiri Nouka people really seem to love chill stories like this.

Reincarnation of the Suicidal Battle God: this one also seems a good choice for all the action and the edgy story

Reality Quest: I can see this being picked up for the wish fulfillment angle of bullied gamer becomes badass through a gamer quest mechanic similar to Solo levelling.

Manwha I'd like to see get an anime:

The Knight King Who Returned With a God: I'd like this as it's actually a positive take on faith plus the main character is a cross between King Arthur and Doom Slayer.

Devil Returns to School Days: this one is more for how fucked up the mc is and story can get, kid is put into a coma for years thanks to bullying attack, listens all that time to the his world crumbling around him and regresses to just as the bullying starts to get revenge. Would love to see this animated especially what happens to the person that instigated the bullying on him.

Return of the Mad Demon: as before, would love to see this animated just for how crazy the MC is and how funny his actions can be.

Ones I have reservations being turned into anime:

Lookism: it's a great fucked up story that is just getting more fucked up, wait let me check......yeah it's cults again and a suicide, still fucked up but i don't think it'll translate well in an anime.

The Greatest Estate Developer: this one is for two reasons, 1. Is there is a difference between the original web noval and the Manwha adaptation which i think is WAY funnier and 2. I don't know if they'll capture the emotions as well in animation between the funnier parts and the more somber parts, if it were to be done I think they'd have to approach it a little like Stein's Gate.

unOrdinary: set in a world where many have powers, it's a good story but I worry they'll have to skip the character developments that take A LONG time to adapt it.

So that's a few I'd like to see in the future, hopefully Solo Levelling is such a success we see more of these adaptations done justice, we now just need the Japanese to fuck more so we can get more animators!
