I have created many constructed languages, but most aren’t in-depth and basically only exist because I enjoy coming up with new words. I don’t have a favorite, but I like ones with interesting grammar such as Goptjaam, UNLWS, Drsk, and Fith among others. That said, I’ve gravitated more to looking at other people’s conlangs as I got older. It’s been a while since I really tried very hard to create an interesting conlang.
