I see. Why don't you try your hand at making a game about Elves yourself, then? Maybe one about Elves making toys at the North Pole? If you start now, you can finish developing your game by December, which is a good time to release one about Christmas Elves. 🥰
Back when Xianxia VNs weren't many, I put out a few of them out on my own. Now there are quite a number of them. I got a message on Reddit too saying that my VNs had introduced the user and their partner to Xianxia, a genre that they now love, so making our own stuff does also help to grow interest.
Gotta start somewhere~
