well, this is natural consequence of Patron model. Most people and especially those from richer countries will not miss one or five $ each month so this can continue for years

Just look for SimBro - Dev died years ago but Patreon is still taking money from people.
And frankly speaking, beside ethics of such behavior of ICSTOR... well, most of people would trade places with him. Not working for months, no stress in workplace, no fear of getting fired, unlimited free time and much, much bigger paycheck then most hard working people

He is gaming the system
It is just shame that he will never finish this game properly

If he would not start milking, then the amount of content he recently promised would have been done in 2019. Shame :/
