in fact this is the "patreon system" who encourage to be slow has possible. The more slower you are the more money you make, this is a fact and this is absurd. In all of history on our economical system, you'r paid WHEN you sell a product or a service and that is the best way to do. Who want to pay 5$*12 (60$) for just one update, this is absurd but yeah, this is the system so...
I've kept an eye on this thread for years now, but I'm very hesitant to bother with it, let alone support it for those exact reasons.
For games of a proper scope the Kickstarter system actually is a lot better. You plan your features, budget for them & set stretch goals for which you also budget.
But nothing's infallible, we've seen Kickstarter projects fail and never get delivered as well. But at least, if it delivers ... you get a finished product.
As for Patreon itself ...
Patreon encourages the 'never ending, ongoing' type of game DEV. I've seen several games of that type, that've been in DEV for years upon years and years. However, it only works if your monthly payments actually get you a decent return.
Otherwise, you kind of feel ripped off. Like you mentioned, $5/Month is a full $60 game each year, so (independant of this specific game really) ... if you get like half an update with maybe an hour of game time for that ... yeah.
On the other hand, I also don't like the perpetual DEV cycle itself, since a game can be milked forever. It's like ... never finished.
4 years, 5 years, 6, 7 years & more ... just keeps going. I'm not a fan since I never like getting into the game as long as it's not finished.
You either end up with an unfinished story (thus cliffhangers). Or if there is some kind of story resolution, you'll always have played the lesser version. I don't tend to replay games, so playing an incomplete thing kinda sucks.
Going back into a game just to check out 5 CG's & some story tweaks ain't worth replaying the whole thing either.
P.S.
That's my take on it though. I do feel like there's merit to the Patreon system for the DEV if they wanna go the perpetual DEV route or don't have enough certainty to budget up front (and also, a 6 year delivery time on a Kickstarter ain't gonna fly).
And if they offer a steady stream of updates, I'm sure many people will like that well enough.
