In Duma Key, several things have happened.

Nick Lothario had been having a very secretive affair with Frida Goth. His wife Adriana finally found out and threw him out of the house.
Brad Burb got drunk and did something very disgusting, and his wife Tiffany threw him out.

The teens have been up to things, too:

Johnny Burb and Daniel Pleasant have fallen in love, having discovered that they are both gay.
Mortimer Goth is in love with Mary Sue Oldie.
Bella Bachelor is rather taken with Don Lothario.
Brandi Newbie is rather fond of Michael Bachelor.
Skip Broke likes Jennifer Pleasant and Nina Caliente.

Thus the 'canons' of the game are getting blown up all over the place.

I used Nopke's character creator to create 10 townies for my town. It seems to try to overpopulate the area with redheads. (Only one of them is a playable Sim right now)

I also used Nopke's character creator to create townies for my military base and noticed so many redheads in town. Good thing I like redheads! I do love that mod because (a) it's so easy to create townies and (b) I think the townies come out looking very interesting, with a lot of variety (except maybe hair color).

Well, my Romance Sim certainly finds quite a few of them to be very attractive indeed.

My Knowledge Sim, whom I figured would be the kind of stereotypical 'nerd' character, is surprising me a lot by being quite attractive to several female Sims.

He did hit it off really well with a townie named Katy Ternynck, who is a Family sim. Since their romance started off pretty fast and did well (it is Spring, after all), she quickly got the want to get engaged to him. So, I decided to get them engaged and moved her in, with plans to move them to a bigger house because the one they are in is a mini-starter that has no rooms for potential kids.
And as a Family sim (and ACR), those two are definitely gonna have some kids and will need the room.

I've got the initial families set up in Camp Jejune and they are working on their careers and having babies and stuff. I'm starting with five families and then I moved several townies into the Barracks because I really like the townies that were generated. I may or may not play them into the neighborhood--that depends on how interesting they are and if they form any love connections. I would like to have at least 6-8 playable households as the foundation for building the town.

Attached are several pics showing the Camp layout and my starting Sims. The Harvies were my first family so they already have a child. They are a criminal family who live on the outskirts of town: Wenafrid is the brains, and Robert does the tech. Everyone else lives on base. The six with no last name in grunt uniforms are the townies I moved into the barracks, and all are currently military recruits or elite forces.

that looks really good @sturlington ! I like the military base idea. Could make for some rather interesting stories and drama.
