Actually, Patreon system is almost perfect, if there's honesty from the artist. Do you want to support an artist lifestyle? You can, just sign up and keep paying until you change your mind about them. Do you want to 'buy' a product? You can, just sign up right after the artist releases something, pay the amount of money you think their creation deserves, and then unsubscribe a second later. In this particular case we have more than enough info to adjust our expectations and choose what to do with our money: a big map, a lot of girls and side stories to tell, a very personal artstyle that takes time to be done, 6 updates released so far (each one bigger and 'slower' than the previous one), and daily reports that show the development pace - so all of us can easily infere this is going to take a while. Sure, all of this lead many people to think it's not worth their money for whatever reason (mine is they're doing more than OK without my financial support - and here you have another bit of info, as they don't hide their income figures as others do), but there are almost 2k people who are happy enough with it to keep funding this project and its creators. And they are not 'wrong' nor fooled into a con, they just have other expectations than those who freely choose not to spend a single buck on this. All I'd hope from non-supporters is to at least be honest and not spread lies or insult the devs and the actual supporters that, in the end, make the game possible and free for all.
