I really understand how he got 650 patrons in 10 months.
I think it's a combination of factors:
- The theme. Cool sci-fi story with transhumanist undertones.
- Fan-service driven porny bits. There is an entire sorority of attractive, successful women who are all inexplicably single.
- MC's ex-girlfriend as the primary antagonist. She is designed to be easily hateable, and there is nothing more attractive to porn game audiences than justifiably hateable women. The utter rage on the Artemis thread is... something.
- Attention to detail. Very high production values (especially after the first chapter), excellent visual and sound design, with dozens of immersive, non-sexual animations.
The updates are very long and are delivered at impressive speed. Chapter 3 took only ~5 months from start to finish, and I still have a hard time believing it. Either digi.B is doing this full time, or he's working with a team.
My only real criticism would be about the porny bits.
This comment summarizes my feelings perfectly.
Still, it's a very good game and I'd definitely recommend it.
