It's something really funny in AVN industry. People want to earn money in game development, but they illegally use licensed renders, so they can't put their creations on Steam or GoG and then they cry about piracyWe are in something really funny in AVN industry, at least in occident. People want good quality matertial, with fast release pace, but only few want to pay. And this bring us to many good AVN being abandonned. No editor mean no job for the dev (creators), only way is to use means like patreon with highly priced tier to hope to get a descent amount of money, and due to Patreon content rules, creator need sometime to adapt the game. And so far it's what work best for the devs.
I'm perfectly fine with paying 20 bucks or more per season, but not if I have to download it constantly via bloody mega or other file sharing service.
Artemis is on Steam, Swordbearer is on Steam, 0 End is on Steam, Love of Magic and Being a Dick are on Steam, and few dozens other. I think BaD even ended up in Steam Top100 sellers at some point, but sure, let's blame the community and not the legal status of the game which is officially - nonprofit fanfiction.
