Superbia

Definitely Mylen for both categories, although Ragsmuena is a close second for gameplay.

1. Mushishi 2. Kara no Kyoukai 3. Crest/Banner of the Stars 4. Juuni Kokki 5. Love Hina 6. Toradora 7. NHK 8. Spirited Away 9. Almost everything from KEY 10. Naruto Naruto gets a lot of flack for its fanbase but it was still pretty amazing.

There are a lot of factors that go into the emotional attachment I have to my favorite visual novels, and to games in general, but the two that stand out the farthest are moments and music. The best games have those scenes with moments so genuine they shatter you. Characters that struggle with weakness probably produce these the most for me. Not hetare, but weakness that you can actually relate to and understand the difficulty of overcoming it. A lot of stories are about facing the wall of limitation and climbing over it through blood, sweat, and tears. Those are great too, but I've always found the moments that stay with me are the ones where that character gives it everything they have and fails, not because they didn't try hard enough but because sometimes everything you have isn't good enough. The characters that are able to accept that and move on are the ones I end up admiring as really strong, although they aren't always the stars of the story. Music is a big factor as well, though probably for a much more biological reason. I've decided to play many games after hearing one song I enjoyed from their soundtrack on Youtube, just because the picture the music painted was so good I thought the game just had to be amazing. It's harder to put a reason on the musical attachment other than just loving music in general though.
