(Ripple Decisions) - This is a huge ask as this story is meant to be linear but they're never off the table if they can be done in the right way fit for this game.
(Pregnancy) - This can only be done mechanically and logically at the end of the story. After all, Maria's reveal would have hit different if she were pregnant.
(More ways to earn income) - A farmable garden is planned to be introduced in the next update which will allow you to grow various things, some of them being money crops.
(Hotel Upgrades) - What would you like to see? Visual changes are impossible with how this game is designed.
(Hiring staff) - What kind of staff? We have Lin and Android to take care of most of the stuff, and Sylvia becomes a cook in her story line.
(Marriage) - Will most likely happen when the story suits it.
(Political Drama) - On the way :)
