These are all great ideas. I'd love to be able to take her fishing or perhaps we could learn some sports together in the rich area. I'd love to be able to taker her places where she can find a hobby other than arguing online.
Moving out to a better place is also something I really want to do. Finding a new apartment in the rich area or maybe even a house somewhere would be very cool.
Disclaimer: I'm not done with the game's story yet and it's my first time playing so the following suggestions may already be in the game.
I'd like to be able to take her to see my friends like Shanice and Priestbot and Mrs. Fisher. That would probably be very cute. Additionally, I'd really love to have some dialogue options with Shanice and Priestbot after the end of their story. That way it doesn't feel like they're just another shop for us, the player and not the character, to use.
