I think this game and Harem Hotel fall into the same struggle pattern: You've created a game where there are so many characters to keep up with and such a different style of game, that it is hard to find the drive to put anything of meaning together after a while.
There are some titles that can still keep adding content time after time and we all enjoy it immensely (Take Being a DIK for example), but Mythic Manor and Harem Hotel strike me as the same game with the same flaw: you've spent too much time and taken too much time to finish it that there is no longer a fire burning for the work. You've done what you wanted to do and turned it into a job and now you can't stand it. The fire and the magic are just simply gone. That pattern follows a lot of creators and challenges that people cannot seem to overcome because now that they are making all this money the passion has turned into obligation. And when things go from "I enjoy this" to "I'm expected to keep doing this" it changes the dynamic of the game, the characters, the story, and the outcome.
This title is no different. And I'm more than willing to bet that the dev is sitting back and enjoying the money piling up while pushing out content to a little trickle in order to maintain the income but not the outcome. It's a damn shame because titles like Mythic Manor, Harem Hotel, A Wife, and Mother, and others were pioneers for the longest time. But then in the back of the mind of the devs you have to know that they're thinking "I don't know how to end this." or "I don't know if I WANT to end this and disappoint everyone." so they drag it out. They milk it. They give small updates in order to get to a point where we may say "Oh. It's such a shame that they died before they finished this game." and just accept that we'll end up with an unfinished product.
People will still continue to sink money into a failed and flailing project because of the potential that is there and this and Harem Hotel are OOZING with potential...but I highly doubt we'll see a finish line any time soon.
