I don't want to criticize your opinion, but I'm glad that many people think differently. Otherwise there would be a lot less choice of games in the forum, or the abandoned rate would be significantly higher.
You're right. Without patronage many games would never get off the ground. That said for every game that completes, 10-20 games are abandoned or end up getting updates 24-36 months apart and won't ever be completed. I don't think that most games are abandoned from a lack of patronage. In my unscientific opinion, most games are abandoned either from RL impacts on the developers, or their lack of appreciation of just how difficult it is to create ANY VN/game let alone a successful one.
It's important to realize, that regardless of their view, patrons aren't supporting the development of a VN. They are supporting a developer or a development team,
whether or not they produce a single update. Literally gifting them money, which the recipients can spend in any fashion they choose.
I want to be clear that I think the developer of this game is honorable, transparent, and responsive. My comments above reflect general problems with the patronage model, not issues with this dev.
----------------
Now there is value to a dev putting a game on this site. That value is "free" testing. Very very few developers have the resources to fully test their games. When I encounter a bug or issue I take the time to fully document and report it to the dev, as do hundreds of others. The goal of most devs is a completed fully debugged VN/game. I've been developing software for over four decades. An hour of my time is worth well over several times typical subscription price of a game. So while I won't give a dev money through patronage, I do provide debugging support and if they care to take advantage of it beta testing.
I don't have that relationship with this dev, but there are a number of popular developers whose games/VNs I provide that kind of support. In a sense those devs and I are mutually accountable. That is a relationship that I do support.
