I have three Visual Novels rated 10/10. Two of them are Key, (Kanon and Tomoyo After) but one lucky other managed to break through~
It was full of plot holes, a bit rushed, and felt like an unpolished Sharin no Kuni (A VN I didn't like much)
Buuuuut, somehow this Visual Novel stuck with me. G-senjou no Maou is pretty amazing in my opinion~ It gets a bit of hate, and I doubt many would give it 10/10, but I have a weird taste ^^;
The main character was interesting, the side characters were interesting, the format of the routes worked really well, and as I am an ENTP with stupidly long hair, Usami Haru really stood out for me~ Ahaha~ I'm the type of person who rates a VN highly if I actually manage to like a character~
The main route was full of adrenaline and excitement, which is what keeps me interested and reading.
The soundtrack was a mishmash of all the famous classics, and it was wonderful to recognize little bits of inspiration within each track~ (Bach and Pachelbel <3)
The H-scenes are there... and creepy stuff like that always scares me away from a VN... but they are incredibly easy to predict! So just close your eyes, press the skip button, and wait for the BGM track to change! XD
Not a story that everyone will enjoy... and it can feel incomplete from what I've heard others say about it... but I love it~
I've tried Umineko a bunch of times, even finished it... But I never payed much attention to it.
CeciltheDarkKnight kept recommending it to me as he's a biiig Umineko person, but it really takes effort to get invested in Umineko.
I ignored the anime because the few episodes I saw of it were definitely badly done in comparison to what I remember of the VN.
