It looks like that I'm a bit late to this thread, but that would probably be appropriate since I just reinstalled TS3 today. :D
I hope you enjoy Lucky Palms, @Lucy_Henley it really is a great world. I also am lucky enough to own all the store worlds too, but my favorite is definitely Aurora Skies. It plays well, nice layout, really nice premade families, and it's just beautiful. Almost all of my legacies end up there. So, if you're still looking to purchase more worlds that would be my suggestion for your next one.
Also, thank you posting about Mesa Grande @Satanu_Reeves I've also never heard of it and just downloaded it. I've only been playing TS4 for awhile, but I guess I got nostalgic over the Christmas break and just reinstalled TS3 with all of it's EPs, SPs, and store stuff. :)
