I believe I bought them in order so Outdoor Retreat would have been my first I think. I got my game Christmas of 2014. The sims 4 iteration I own all of the expansions, game packs, stuff packs and kits, and some of the maker packs. I play on laptop, but do not use CC or mods.
If I were to start the Sims 4 game today. I would most likely start with Growing Together for Infant upgrades and likes and dislikes, then LoveStruck for the turn on and turn off’s ( I like the colorful world too ). Then Get Together, Get To Work, Hobbies and Business, Island living and then the 3 animal packs. Parenthood would be my first game pack, and then Outdoir Retreat, and Wedding stories ( for the world and clothes ), spa day and the interior designer pack. I really anticipated Dine out, but it has flaws and bugs. The only expansion I was really disappointed in was Discover University. And I was disappointed in how small the Get Famous world was. I’m disappointed we never got car,s bands, casino’s, hotels, volleyball, pool tables, and being able to throw baseballs.
