@RandomWasabi Honestly most of them aren't exactly that good. You have
Arifureta Shokugyou de Sekai Saikyou which is definitely an ok manga (not a fan of the Anime so far) but that's more your standard run of the mill isekai with a seemingly very far in the future revenge plot.
Dungeon Seeker is... yikes really edgy, but completed so that's neat. Honestly almost no plot at all wouldn't really recommend but it's there.
Kaifuku Jutsushi no Yarinaoshi is a bit similar in terms of setting, I was intrigued at first but it's really not that good, but the world seems really really similar (messed up people left and right). And lastly
Nidome no Yuusha I guess. Very similar outlook.
These are what I would consider very close in terms of setting. But I wouldn't actually recommend anything other than Arifureta if you're into Isekai. Following entries are definitely not the same but do share similarities in some of the key areas imo and are better than the aforementioned. And might scratch the same itch:
Isekai
Goumon Hime (Torture Princess), it hangs around the same rating but it's vastly superior to the other entries imo.
Dorei Yuugi as well as
Battle in 5 Seconds After Meeting have normal people kind of devolving when social norms are not hindering them anymore (maybe
Ore no Genjitsu wa Ren’ai Game?? ka to Omottara Inochigake no Game datta ) and
Game of Familia: Family Senki has a very driven main character like in this one.
3 favorites of mine here would be
Akumetsu,
Alice in Borderland and
Arachnid. But I think these are the most removed from this setting so yeah. Do take it with a pinch of salt but I think you can find something in here that would suit your taste.
