So many ways to answer you, my favorite is from the Reading Rainbow Kickstarter:
"Reading Rainbow was one of the best parts of my childhood. I don't care if LeVar and the staff blow it on blow and hookers, have some of my money."
I have a file on my computer that is 100% porn 76GB. 46GBof it is (shudder) real people. The rest of it are characters, drawn or animated. My favorite artist's is 714MB in size. SR7's is 9.71 GB. Most of it is screenshots from this game because we can't do save files to relive conversations in real time. Almost 10 gigs, and the man has never received one cent from me in commission work or patreon.
'Fair' is a bullshit word. A politician's word. A word that exists so guys like you can sit at your desk and have some benchmark to complain about. There is no fairness in porn games and animation. If there was then guys like SR7 would be held to greater transparency for the ~10k you say he earns a month; and there'd be a commensurate transfer of wealth for the value crooks like me get from all the art and gaming assets he's made. Idk how many people have downloaded this game's versions over the years, but if they have ten versions on their history like I know I have then they are monthly benefactors, and since the US is 325,700,000 (that's over 325 million) people it's not hard to imagine a piddling little number like 10,000 download it like clockwork. Asking a dollar from them all per version don't strike me as much at all. Maybe the number of downloads is actually much larger, and the man earns half or maybe even 10% of what he deserves. Things would be different if this were a fair world.
But we don't live in that world so people, who pay more than they reasonably should, complain because they feel they're owed something extra for the money they voluntarily dish out, and people like me keep our heads down, popping up occasionally to give the valid criticism or heartfelt praise, to the man who gives us something we hold in value while he receives nothing from us in return.
Now if you'll excuse me, I'm going back to my game. I owe a fella screenshots of dialogue between Killer Frost and the other henchwomen, and I suspect the screenshots of those images will bring me right up to my full 10GB...
