The Crucible is a good way of getting money and experience if you keep replaying it.
I've made more money off buying stores and stalls rather than renting out houses. I dunno, maybe it'd make more if I spent time to redecorate and all that. After buying enough stuff, it's easy to start generating a pretty sizable income.
I got married twice, but I ended up losing them. Too much of a time suck to go and visit them all the time. Never bothered with trying to have kids and all that.
