I would love more seasonal activities especially for spring and fall. Summer and winter got several activities, but spring and fall feel really missing? What do we get for spring? Play in mud/rain puddles? The flower bunny tradition? Meh. Let sims plant things, pick flowers and make flower crowns maybe, would go with the flower bunny bit and actually give them something to do. And fall gets... the puddles again, and the leaf piles. The leaf piles are fun! I like having my sims rake their yards and then play in the piles, but it's basically the only fall activity? Let my sims collect colourful leaves! Let them fly kites. This is the fall activity I'm most disappointed about not having. So many worlds in the game have lots of windy fall days. Perfect for kite flying!
And yes, the holiday activities absolutely need updates! Club activities and now the small business activities have been getting cross pack integration, it's so disappointing that holidays were never updated for new pack activities. It's such a cool flexible features to customise our sims' lives, I use it so much in my game, but already the holiday activities that came with the Seasons pack are pretty limited. I have to download cc activities to make holidays around seasonal activities from the seasons pack! Why do I need a mod to get "play in leaf pile" as activity? Why is that not part of the pack? Why are the various "do seasonal activities" selectable as club and small business activities, but not as holiday traditions?
Activities from the Snowy Escape pack would be great for additional winter activities. Spooky stuff has Halloween traditions. New Year's Eve with fireworks.
But what I most miss is cultural traditions from more cultures? They gave things neutral names like Flower Bunny and Winterfest, and you do get trationals like lighting menorahs rather than Christmas trees, but it's still pretty limited. The game has so many different sim cultures by now, based on so many real world cultures. Why are my Sulani sims, who live in a world with its own district culture, stuck celebrating Winterfest? I want to make island holidays with island traditions for them (and I do, but it requires mods, thank you modders). The sims of Mt Komorebi also would really like to celebrate their holidays, maybe with nice family hot pot meals. Let my sims celebrate Carnival with colourful outfits/costumes. We got Día de los Muertos outfits a while ago, where are the traditions to match it?
We also have all this pride merch, but with the existing traditions, it's really hard to make holidays for it that really work.
And let me decide which surprise holidays I want in my game. I find talk like a pirate day hilarious, but neighbourhood brawl and the lottery day? Meh! And I know other players who hate the pirate day, so please let us pick which holidays we want to play with.
I also would like to be able to have activity events and events with goals on holidays. I can have base game dates on holidays! Base game dates are goaled events! Why are they the only goaled event that works?
