@RunAmokSims -- thanks for the link to the story about the evil Sim -- it was very entertaining.
@judewright -- So glad you got the demo! Hopefully everyone will be able to get it soon.
Reading an article by SimsNetwork, I learned that there is a 19th skill -- gourmet cooking. It has its own set of skill books, and apparently each skill has 3 books that you can read.
I've been thinking about how I'll play this and what kinds of stories will be possible. Besides dynasties and other generational games, it looks like we'll also be able to do rotational play. That's where you can control several households -- even all households -- in a neighborhood or world. It was possible in TS3, but you lost relationships and wishes whenever you changed households, and with story progression on, you might even lose a household you'd been playing if no one in your current game had a relationship with them.
That said, I'm thinking about moving some of our friends from Sunset Valley into TS4. Hank Goddard and Pauline Wan, for example -- but into separate houses. In TS3 it was fairly easy to get them married to each other despite their fear of commitment, but how would things work in TS4? Then there are the Wolffs. Secret Agent Thornton Wolff has been lying to his wife all this time, telling her he was in Business, but now he's also lying about a growing relationship with co-worker Jamie Jolina. Will Morgana discover the truth when she takes up a career in Painting, and if she does, what will she do about it?
Basically, we had to manufacture our own drama in TS3, but I'm curious to see how much some of the TS3 Sims will do if they're put into TS4.
