A three month arbitrary deadline for updates is a ridiculous thing to try to apply to every game, but the 12+ months this game takes to release a full chapter is equally ridiculous.
The updates are never going to be faster for this game though. They've proven that over the last 3+ years. This thread will be a happier place when everyone accepts that.
The key word is "artificial". In 2017, most games updated monthly. Things were in sync : one update in return for one monthly subscription fee. This time-frame is also the most common IRL for most larger money exchanges for the average Joe/Jane.
The other most common big-organization IRL wealth-exchange is quarterly, or every 3 months. Next would be yearly.
Without a hard-and-fast timeframe for VN production, the average interval between updates has probably drifted to at least 6-7 months (more if games like
Polarity are counted). But payments have remained on a monthly basis.
The payment system, pioneered by Patreon, is broken badly for paying supporters. But for Devs, especially, the present situation is great. Less work for more money.
Not one of the several shill-posters that post in this thread will admit that supporters generally get a raw deal. In their view there is no problem to fix. Dev paradise.
Meanwhile, what is almost certainly the main cause of Dev burnout, blow and hookers or somesuch similar, is NEVER mentioned.
Losing the discipline of regular work by stalling/milking, and somehow still getting paid, is not viable for most people even if they laughably call themselves "Creators".
