In my eyes, Get Together, Cats and Dogs, Seasons, Get Famous, and Discover University are true expansion packs expanding the foundation of the game.
Get Togethers club tool is insanely useful for literally whatever you want to use it for.
Cats and Dogs, cats and dogs I personally believe are the best in the series, many disagree so do your research on that one.
Seasons calendar and holiday creation tool is a game changer. Also the seasons themselves are stunning and have a real impact on progression and daily routines.
Get Famous’ fame system expands literally every career and hobby in the game, it also adds a form of hierarchy into the game. The reputation system also adds another layer of depth to the sims.
Discover University also expands every single career in the game, it’s also just a great opportunity for your sims to build relationships and skills, great for story telling.
Parenthood is the only game pack that expands the foundation of the game, great for story telling and family play.
