Get Famous vs. Get to Work

I think I'd go with Get Famous, because it adds fame to all the jobs -- I have a couple where one is a famous artist, the other a stylist/writer. It expands the entire core game play. Plus you have the reputation system that adds a lot to gameplay. You also have more objects that can be used by Sims, like the video production station and the audio mixing station. Many of the objects in GTW are restricted to Sims that are in that specific career unless you use mods to unlock them.

GTW comes with a small world (Magnolia Promenade) plus 3 hidden lots for each of the careers. I personally like Magnolia Promenade -- I've made it my entertainment district with a bar, a lounge, a nightclub and a karaoke bar (I have City Living) so it's a good place to send Sims for a night on the town. (I'll probably resurrect one of my teen clubs when my current child ages up). I haven't done a whole lot with retail recently, but I am planning to have my artist open a gallery soon.
