It was a nice watch. The market is very niche, most of the people I've talked about VNs they only know stuff like Fate, Steins; Gate, Nekopara AKA the popular stuff, so the market tend to be specialized to a certain group instead of general audience.
A trend I noticed is companies translating gachas, they bring a lot of revenue, are very short and the story format of most of them is Visual Novel like but earn the money (mostly cause the gambling and FOMO). People praised Fate Grand Order a lot when it was released because of being a "Mobile phone with a good story" yet they only stayed playing gachas not tried VNs . I feel like I've seen more gachas being brought to the west than VNs.
However, I feel like VNs on the west are on a better place than before. Stopped reading VNs some time ago since didn't find anything interesting and read most stuff that was popular, it was kind of amazing coming back and seeing that there was a lot to choose from.
