I just have a Nicki save as well so far.
This is pretty much exactly the kind of things I want to do too in-game. If I woke up wealthy, not sure. Probably too introverted and asocial to do all that, so it would probably be charities for me.
We also have Cassie to deal with, I'd like to reconnect and be the brother I haven't been in a long while, and help her deal with whatever shit she's in currently. At least I can put her up in Nicki's 'old' room (what a coincidence that became available just now) while we sort out her situation.
I would not be surprised if she brings chaos with her. Bad, horny me would deal with that in interesting ways good horny me will only fantasise about. Poor good me.
