What to buy next?

I'd love some advice on what to buy with the current sale going on. I have most EPs and SPs but not all. Here's a list of what I do not have: Into the Future, Fast Lane, Sweet Treats, Diesel, Movie Stuff, Roaring Heights, Aurora Skies, Monte Vista, Lucky Palms, Sunlit Tides, Lunar Lakes, and Barnacle Bay.

I'll eventually get them all..or at least most. Admittedly, I'm particularly interested in Fast Lane. The ones at the top of my "buy now" list are Into the Future, Diesel, Roaring Heights and Movie Stuff. I'm already 100% certain I'll get Diesel but the rest are still up in the air.

Soliciting and welcoming advice and opinions from all! I'm easily persuaded!

Of your list of what you don't have some are better and worse on varying degrees.
Into the Future (not bad good content I don't really play with the features), Fast Lane (pretty pointless in my opinion), Sweet Treats (Not really worth it unless you love Show Time), Diesel (Not too bad I liked this one it did wonders for CAS), Movie Stuff(Again not something I really use and my current sim has barely gotten into her actress career.)

Roaring Heights, Aurora Skies, Monte Vista, Lucky Palms, Sunlit Tides, Lunar Lakes, and Barnacle Bay.
As for the different worlds, Aurora Skies is my favorite, but you can see what they look like and decide upon which one you like based on how you like to play.
