Define "quality of others"please. The way you speak about it - it's like you rely on common opinion or reviews and are biased even before you start playing it.
For me quality of the game/story is what this game makes me feel during my playthrough, the game can have high quality renders & animations, outstanding music but if it bores me and makes absolutely indifferent toward characters - then it's not good game in my opinion.
It's always subjective of course, and alsoI consider my self picky person, but I can tell you that this game is one of those that you can't stop playing until you finish it. The universe, the lore, characters - everything is set up in a best way for your immersion and enjoyment. So I would say you either played the game not in a way it's supposed to be played (like clicking through dialogues for lewds for example) or you expected this game to be smth it was never meant to be.
I also confess that this game made me fantasize about certain characters (Medb to be precise
) which is a damn rare thing for me.
As for games you mentioned, like I said - it's subjective of course, but I am curious, if you consider CoBD or DeLuca Family average then what is top notch for you, Grandma's house? WVM?
