I find Seasons to be the bigger EP to get. If you're a family player you'll definitely get a lot of that out of Seasons considering your sims making big grand meals to feed family and friends while calling thema special way to the dinner table and everyone actually sits at the table, gift giving and having a proper holiday for sims to share that thankful spirit it just kinda give me warm fuzzies being able to properly decorate my home (in someitme stack fashion) with holiday decoration.
Definitely a overhaul where they'll have certain stalls spawn in commercial lots along with skating rinks. Where the big pirate ships and space ship for kids are I noticed three waterballoon buckets.
Another pack I enjoy is dine out. Having sims having a proper place to go out ot eat for family dinners and dates is also a must.
