Which pack has been most influential in your game?

Seasons. The pack affects everything. Adds so much variety to the worlds and gameplay.

Parenthood. Children and teens are my favorite stages.

Seasons. I love how the weather/seasons changes the environment. (And for awhile how Winter removed those Townies that thought exercising in tank tops and shorts was a good idea.)

Get to Work. I play a lot of aliens, retail, and active careers.... doctors are my favorite and I never get tired of it.

Tied at the top parenthood, seasons and get together

Get Together.
I use groups and clubs a lot in my game.

Vampires. I still really enjoy that pack.

Spa Day - I use yoga and massage all the time and love the new aspirations.

Seasons has influenced my game play the most. A trip to the park may be canceled due to rain. Gardening was expanded on and that enhanced my spell castor experience as they grew their own herbs to make potions, and it enhanced my pets experience because I can grow catnip. When I keep a garden my sims usually have to stock up enough food to carry through winter as I don't let them farm in the winter. The seasons encouraged me to build a green house for gardening in the winter during emergencies. Honey was a nice edition to add to things to sell as well.
