Whilst ICSTOR, and those who work with him, do stand to make a steady, decent, income as they do now. They would actually make much more money if Milfy City were released.Irrelevant if the final update is liked or not. It will be released on steam where it stands to make some real bank. Take BaD, for example. Sure DPC makes loads of cash money on Patreon but the sales of Season 1 and Season 2, alone, on steam made him 4.2 million US Dollars. 302k units sold at 13.99.
If you want to make the big boy club of money and really live like a king. You complete the game, or sell it in seasons and then sell it on a hugely popular platform.
