Would probably change up a good portion of the game but I'd personally like more options to use the money you can earn in the game like moving out of the apartment you're in, more sectors to visit, a larger map even.
This is a lot larger asks, I know, but with all the options to earn money (and now that I'm sitting on 500 bil in my current playthrough), I'd really like ways to spend it and to reflect the character's better situation even for streaming or just living with their robo girlfriend =)
