So the majority of respondents as of today (6) are claiming to have total income from all sources (including day jobs) of less than 10K$/year.
I'm sure that most people read your poll as regarding the game income, not the whole income of game authors. I mean, what sick person would want to know how much they earn with their regular job ? It's personal and totally irrelevant on this forum.
They earn enough to own a computer, have an access to internet, have enough free time to make a game, and, for those who use it, buy some assets for Daz3D. By looking at the game, still for those using Daz3D, we can also guess if they earn a little more or a little less, by the quality of the renders and the number of assets in the game (or the use of the basic cheapest ones). That's what we know, and it's already more than what we need to know.
You should try to be more consistent. You can't, in another thread, try to lecture me about the fact that living cost isn't the same all around the world, then few hours later decide, in this thread, that poverty wages are the same in all countries.
To keep the India example that you used somewhere else, US$ 10k/year is around 200 time the minimal wage ; so, way above poverty wages in this country. And you don't necessarily need to go this far, in Poland, by example, it's around 1.6 times the minimal wages, so once again above poverty wages.
In the end, you only prove that I'm right when saying that your expectations are pure fantasies. You know nothing about the reality of the adult game scene outside of Asia, and still try to give lessons to people who are part of it.
The vast majority of authors in the scene don't care about the money, they want to make a game, that's all. Many of them said it to you, yet you don't care and look at them like aliens, trying to force the reality into your expectations, instead of correcting your point of view.
But it's just the truth, globally speaking, they don't seek for a living income, and will already be happy if they earn enough to cover the costs of their game. Which lead to another problem in your poll, the lack of negative values. Because yes, many authors spend more on their game than they earn with it ; especially, but not only, those who start.
For a Daz3D game using Ren'py, between the price of the assets, the electricity bill, and potentially a little update of the computer, you can expect a debt between US$ 1.000 and US$ 2.000 when the game is released for the first time. If the game is more ambitious, it can easily go up to US$ 5.000 and more. With, more or less, half of the authors earning less than US$ 1.500 by year, and the electricity bill running, when the game will be finished, most of them will still have spend more than they've earned.
