It's why dev's shouldn't even attempt making an AVN if they also have a 9-5 job and real life. Go live in mom's basement first and make the AVN the job. I would while clearing my schedule and social obligations for the next 5 years before even considering AVN-duty with the thousands of hours and dollars it takes. I know a few dev's that do just that and on average maybe crank out an hour of reading for every 2 months between updates every 1-3 months and write, code, pose, and render all by themselves.
I think a fault a lot of devs make... is that it is 2 hours of reading that makes up the content.
i.e. too much focus on text, like yes you want to tell a story.. but this is a visual medium... so you also
show the story. So you end up with too many words, and not enough visuals, which make it feel shorter, especially when people get tired of the reading and skim.
But if you have more visuals to show the story, it pads it out and engages them more, so what was an hour of reading, that most spend about 20-30min on, becomes and hour of playing.
Although, that kind of thing requires more learning, cause then you need to know more about lighting, perspective/camera angles, setting up the scene, etc. Basically, learning how to make a whole film yourself, but then doing it with images.
