I dont think this analogy works since movies and AAA games are developed differently. In visual novel you need to work on renders and text only (and perhaps models and scenes if those were not stock).
I'm not trying to diminish the work of the devs, it's amazing. But for the trending VN on patreon i would assume it must be their main focus, not some side hustle. I'm just trying to comprehend what takes a year to complete an update.
Well, you need to understand how developing a game like this works, first learn how HS works, then try to render a good scene with a few characters in it, well you will need thousands like this just for a decent chapter and that is simplifying things: No animations, no music, low effort in UI / menus...
There are many low effort games out there with broken English and barely any effort in the models or even animations, but they update faster than this, if that is what you want you only need to search them in F95.
I personally would rather wait more and get very good content that will make me immersed in the story, then just play a very lackluster game every few months.
Even then, with so many great games to play, the wait isn't that bad most of the time and honestly if I forget about the story if the game is worth it I don't even mind replaying between long updates.
