I see where you're coming from. To be fair though...
I wish. This game may not be perfect, but between having an actual story, having
beautiful art and animations, including some proper gameplay, having pretty likeable girls and having a nicely set up world... I think it nails too many things at once for many games to be like it, sadly. You'll find better games if you pick a niche this game offers and just explore that, but all of this game's elements together? Ehhh... I don't think there's many to be honest. There's a reason why, the moment I finished playing the quick, dirty MTL I did for myself, I went "yeah, I've
GOT to translate this".
Of course, if anyone does know games that resemble this game in either themes or quality, I'd welcome them to recommend those! Although, for example, I don't think I'd have enjoyed this game too much if it didn't have the 2nd Route, as I have little interest in "exclusively monster rape" types of games. That's just how difficult it would be for me to find a game that'd make me go "oh yeah, this one was as good as Thanatos". May just be me though, but this game hit too many good checkmarks for me to not love ahahah
