No, that's not what I'm talking about. This game is 5 years old.
lol what has number of years got to do with content?
As Carta has mentioned above, dev does this as a hobby (and actually has a separate main job).
Besides, what actually would be your definition of "content"?
Banging the main girls? lol
Dev has said from the very beginning of the development that main LIs will not jump on MC's bones right away (side girls are exception, because they're side girls lol) and story will always come first.
Sex will happen when it fits the story.
In fact, he has stated that MC will have full sex with all the LIs in season 2 (season 1 is just done, and after couple of extra stuff including Steam release is done, his development on season 2 will begin).
But even with no full sex scenes yet with the main LIs, there has been a lot of content regarding the story, lore & world-building which a lot of people see as content.
It's just that you seem to define content in a very different way (content = banging the main girls) compared to them.
Which would be fine if this was that kind of game, but it isn't.
