I would like to see more involvement with the current careers the game offers. It doesn't have to be a 3D environment either. A 2D office setting with choices on what you want your sim to do would be neat.
For example, if you are employed as a programmer, you can sit at your desk and work. Or you can go to the coffee maker and chat with coworkers. Or you can use the washroom or slack off.
It's completely up to you! And on the bright side, at least it's not a rabbit hole.
