Im sure there were more factors at play at the time. I cant speak for him on that but i know some stuff in his life did happen and that's around the time updates ceased. I've always asked him to be more clear with his followers or people who cared, but he has a very nonchalant take on it all. I think he also just wanted more freedom on what direction to take the game in.
So deal is, I dont think he's ever been into porn content in games, In our friend group 3/4 of us play porn games in general, 2/4 of us play them alot, and only he is indifferent. I remember him saying a real long time ago that he didnt really want to make porn games to begin with? don't quote me on that one.
Now as for finishing the game, People tend to gloss over this a lot, but MGI is done as in whatever comes after will have no porn unless some crazy shit happens and Red changes his mind. I don't know why he wants to continue it in that way but hey that's his prerogative. That also clarifies what he meant when he said the game is done.
just one question - why he keep the wall by only saying one a year "the game is still in dev".
i mean, if people payed money untill the closer of Patreon, a little obligated to show something, just a little bit it's the minimum, i mean, he started in what? 2015-2016 making the game? after 7+ year something out should have come, if not the completed game, something?
with this i don't want to down play the dev of a game, but if people paid me money to make a game it should be my 1st priority to keep in contact and alive, other then reassure that the game is coming alone and sometimes some photo/video to show, this one thing is not hard at all.
linking to "people paid money" it should be
mandatory, even if you don't care or don't want to.
look to other games Discord, the dev and team are chatting and interacting with everyone (even the one who didn't paid a dime).
i think nobody forced him to make a game and start Patreon, but that action brings consequence.
