I've said it before, and I will say it here.
Patreon is to porn games what pre-orders are to AAA games. They both incentivize developers to put in less work as the sales increase.
If Patreon gave a damn about its own customers, they would force the devs to provide a timeline; i.e., "I will complete 'chapter 8' by August 15." Then, during that time, the promised money would be collected and held in escrow.
That way, if the dev misses their promised date, the Patreons could just demand their money back. And even if the dev meets the mark, they Patreons should be given the option to vote on whether or not the promised goals were met, and whether or not the dev should get the money, or the Patreons should get a refund.
That would end most of the drama immediately.
The only downside to it is that 99.999999999999999999999999999999999999% of all Patreons are sniveling simp fanboys that will upvote ANYTHING as soon as a cartoon nipple is exposed.
