Would my novel last on here?
She'll keep going out weekly until June and it is what is.
Have faith in yours and that people who are into it will find it!
That said, actually inviting people who read genre, outside of web serials/RPG stuff, isn't exactly forbidden, and can strengthen your base here. Something probably all genre writers here should be doing anyway.
Second, as FAHyatt said, you can help shape Royal Road by inviting others to take a look at it. At minimum, consider posting a link directly to your story on other sites, such as Facebook, Twitter, MeWe, Reddit, etc., and suggesting that others take a look at it. You can also suggest that they make accounts and take a look at what else might be on the site. The more that other genre fans enjoy the site, the better it is for everyone -- yes, including the litRPG folks.
It's like this. If you like action movies and hate romance, you aren't necessarily going to never watch a romance without someone forcing you. It's just that you'll drop the film for even the slightest of grievances. If you are really hankering for a vampire action movie, you may just be willing to watch and enjoy the Bloodrayne movie made by Uwe Boll.
Any genre can survive on any platform.
Second, what are you here for? Are you here for Internet Points? For exposure for your finished novel? To build a Patreon so you can quit the day job and write for a living? Or are you just here because you feel compelled to write and share your writing experience with others and learn about the craft and discipline of writing?
If it's the last (and I hope it is), then even if you'd like the other things, don't think about them. Just write. Write and read and review and learn and then start again. Views and reviews and ratings and rankings will follow from healthy participation in the process and, once you've got one fiction down, you can move on to the next one and the next one. And at that point, you can think about income streams and publicity and exposure (and even Internet Points, if you care). But don't put the cart before the horse.
