Why is everyone acting so surprised when a game gets big and then basically stops putting out updates?
The creator has made in life with that kind of bank, he/she/it doesn't need to work anymore. Maybe a couple hours once a week to make it look like something is being done, but no real progress.
Its the same with basically all these NSFW games. Heck its the same with the entire entertainment industry. Just look at ASOIAF and the disastrous conclusion of its TV adapation GOT. Or the Marvel comics/movies.
The ship has sailed beyond the horizon, the game is over. Go find something new or a new creator to support.
