I have checked in with the various pre-mades in IL even though I did that and then put them to one side for now.
I don't know that I'll fully play out all of the houses but I did get a sense of where I'm going with some of them.
As for Duane, I said that the Kealohas are fostering him. The local culture is a bit different than others. I'm keeping them pretty isolated and making it a trek to get out there. I'm also playing it as some kind of territory, sims can move there but it has its own local government and laws. I don't let sims hop back and forth between there and the other worlds. I also ignore the Sulanians in any of the other worlds. (Sure, it would be nice to set that in the game settings but I'm fine with ignoring them.)
Anyway, Sulani natives often tend to grow up faster than in other cultures. Lilliana and Makoa married young but have a stable family. They took Duane in at the urging of the community. I'm playing him as an orphan but no, I probably wouldn't pair him with the Kealoha daughter. Too close. Anyway, he's still a teen but I'll keep him playable. I'm not quite sure what he'll do but I know that he will move out and be independent soon, possibly while still a teen.
I've got back stories going for the various other houses, I don't know how much of them I'll play out. I like the idea of it being a tribe with just a few outsiders who need to get familiar with the locals to actually live there ... but I might also add a "resort" on one of the beaches when I get around to it. I just wish I could combine a restaurant and a spa because I only want one beach lot to be like that.
It's a work in progress but lately, I'm getting familiar with Get Famous and revisiting my Windenburg households.
