I'm working on a horror/romance theme park simulator/interactive novel. I would love to say "visual novel" but my art skills are non-existent.

The four VtM Choice of Games novels are really fun, well written and with very distinct flavours. My favourite one is Night Road, but Parliament of Knives is great if you are into high politics, and Out for Blood is a really fun Hunter / Small Shop manager simulator with lots of winks to Buffy and Stephen King. Sins of Our Sires was much more mystical and also kind of broken on release, BUT apparently they fixed it well enough to win a couple of prizes.

From Hanako, Black Closet is as radical as Long Live the Queen and it also lets you play semi-freestyle, shorter runs. Really fun.
