Definitely more activities, when you get to a point where you're rich and don't have really anything to do but sleep to pass time, it gets boring. Also because I have nothing to do but to stream and sleep, maybe add some form of way to show your progression through the story? I know it's a simulator but I have no idea if there is an ending or anything else to unlock at the stage I'm at so it just seems like I'm pointlessly grinding while waiting for nothing.
