Holy shit. This is the kind of poorly-conceived, cash-grab bullshit you expect from EA games. YOU CAN'T HAVE YOUR FUCKING ENDING BE DLC. You can't. And don't tell me "well, it's not the ending, you got an ending, this is the CONTINUATION" because no, bullshit, no. That's crap and we all know it.
He's not quitting, he just decided that you get two options:
1. Be an asshole in-game and get an ending
2. Be a decent man and wind up with a complete non-ending and maybe, sometime later, he might come back and offer a DLC story that continues it.
This is not how you end your first project when you're hoping to get people to sponsor further work.
I can understand your disappointment on the gentleman ending, I'd rather have it finished, too.
But I don't think the criticism you're both leveling here applies.
You don't buy stuff on patreon. You decide to support an artist who - in most cases - eventually releases his product FOR FREE.
Daniels K. has released multiple games already, this isn't his first. All of them are eventually available FOR FREE.
If you do decide to support him, all you get is premium access, which is earlier access to the content. That's all. Patreon is there to support and help finance an artist you like and wish to support so he can keep producing content. You don't buy anything, nor do you have to.
I think it's kind of ridiculous to complain about further content updates on a forum where you're getting all these games for free anyway. Most of us here didn't support Daniels K. one bit. To then be pissed off that he's stretching some content through future occasional updates since he can't continue all plot strands anymore seems entirely inappropriate.
And if I'd ultimately have to choose, I'd rather he do future content updates to give us a great gentleman ending that we'll get - either way - for free anyway, rather than getting some half-assed mediocre conclusion now.
The primary reason the current ending is so annoying is because it's incomplete and unexpected since we expected that we could finish every route. It was a bad decision to not give a heads-up about that, but ultimately if he'd asked: what do you want, a quick finish to the gentleman ending or rather that I deliver some more gentleman content while working on the next game, most people would have clearly favored the latter.
