Acting Lessons and Being a DIK (Season 1, so Ep1-4) are sold on Steam, you knew that, right?There's a lot of this 'piracy' word bandied around here. If the game was purely on Steam say for example, the game was pureluy obtained by 'buying' it...then this is a piracy site.
These games are few and far between. If you accept donations, you are giving your game away. It's free, therefore there is no piracy here. There is no legal jargon to agree to either. It's a free product that they accept donations for. If AVN devs have an issue with this, then maybe they should stop accepting 'donations' and make it purely a paywall product with DRM such as Steam. Even if they could give a dollar a month, some people are so obsessed and indoctrinated with Steam, they will still prefer to 'buy' it there.
However they won't, as they know most of their revenue stream (donated) comes from people on sites such as this. It's a double edged sword. Bottom line is, most AVN's are not sold, they are working on them anyway and accept 'donations' from admirers. DPC apparently whines his revenue stream keeps changing (my heart bleeds), well then maybe charge for your product and skip the donations. He won't (none of them will) as they know purely charging for it won't make them enough money (unless they do it purely for the actual fun of it, and that rarely lasts very long).
I do agree on many other points of your post especially no serious programer is ever going to put a porn game on thier CV.
Just my 2cents on this piracy issue.
It's hard to blame someone in a niche industry from also using a path that allows more direct interaction and feedback from their biggest fans, to say nothing of allowing those people to pay more than retail price (eg Patreon). That's exactly why Patreon exists, and the whales are almost certainly where a majority of the income comes from - for someone whose doing this full time, stability of income is a pretty big concern!
I mean, I'm here, and I get the other side - I tried this game without paying, and I'm far more likely to pay now! (it is the best or the 2nd best game in the genre, in my opinion). So he definitely benefits - but he gets that benefit regardless of whether he's active here, and it doesn't come without associated costs. I don't think it's unreasonable to understand why a creator could have mixed feelings about that.
