My top 2 choices would be: Community Careers and Car Life.
- Community Careers - It'd be nice to have 3 new in-depth active careers - looks like dentist, firefighter/EMT, and hairstylist. I know firefighter was an active career in the Sims 3 and I enjoyed it back in the day. Maybe we can even get a refresh on the 3 careers from Get to Work.
- Car Life - A high must, new drive-in movie date spot if you have Lovestruck, being able to teach teens to drive, collectible toy cars for kids, all that is awesome.
- Suburban Living - The active careers fit in well here and an excuse to get to know Sims in the neighborhood. I would like an option to lock down some sims into specific neighborhoods like keeping celebrities in Del Sol Valley so we can have a bit more townies per neighborhood and less repeats.
- Work on Wheels - Although we don't need yet another side hustle/career around food and stuff, I wouldn't mind having food trucks or mobile businesses. Could see some cross pack gameplay with Get to Work & Businesses and Hobbies.
- Ocean Exploration - Could be interesting if there's some cross-pack play with Island Living, expansion on mermaid and other marine life.
- Van Life - With the way the game has an issue sometimes rendering worlds or traveling between worlds/lots, I'm not sure how feasible this is for everyone's PC. Also would be a bit confusing if the Van is considered the Sims "main residence" or like a vacation spot like how they do destination worlds. Could your sim own a home and a van?
- Reality T.V - I think it's a bit too much of "Inception" - a game within a game. I don't want to navigate my sim playing in a reality TV show.
We'll probably see bits and pieces of all of these over time but I am interested in seeing how cars/transportation plans a part in like 3 of the 7 themes. Makes it seem almost like a guarantee cars are coming to the Sims 4 eventually.
