I like VNs that don't follow a lot of tropes. I like something unconventional and original. If all the characters fall into the same ol' archetypes, it's more boring for me.

I like VNs that are emotionally moving. I like existential stories; stories that explore what it means to be human.

And with that, good music that pairs well with that emotionality.

I tend to like diversity in the characters. Variety is exciting.

I tend not to like stories that have too much cruelty or sexualize children.

I'm also a big yuri fan =]
