It's long but full of awesome concepts! The first one is funny for me because I was thinking about the same concept today. I think adding a phone and being able to call guys like Franklin (those who are single-time meeting now) to invite them for sex would be cool!
For a baby thing, it sounds interesting to have an additional source of income from a father (for sure Vito won't be interested in paying it lol). The point is to avoid actually showing the baby because it's totally uncomfortable and not very appropriate for that kind of game xD My current idea is whenever the baby is born it's automatically collected by social service. But it's a bit cruel. I will think about it.
Thanks again for sharing your suggestions! <3
