what stuff pack to buy

@Carpincho54that is hard to say since no one knows you and what you like and don't like! 😉
For example, I love family gameplay, so my favorite packs are the Toddler Stuff Pack and the Kids Room Stuff Pack.  But if you don't like playing with toddlers and kids then theses would not be the best choices for you. 

Other than that I really love the Movie Hangout Stuff Pack, the Vintage Glamour Stuff Pack, and the Tiny Living Stuff Pack.   However, at the end of the month there will be the Nifty Knitting Stuff Pack, and since I am an avid crocheter and knitter, I am pretty sure this will be my favorite Stuff Pack. ❤️🥳

But if you tell us what you like and don't like, or what you are looking for, then maybe we can better help you! 🙂

@Carpincho54 I agree with @PugLove888 . We all have our own way of playing this game and my style of playing might be very different from yours. Personally I think my favorite stuff pack is Bowling Night because I usually play a household with just a single Sim and having a bowling alley gives her another fun venue to hang out with her friends. The bowling alley I created is a combination Bowling Alley/Arcade/Karaoke bar. It makes a great club house if you use the Get Together EP club system. My Sim has an NPC family (mom, dad, sisters) and they have a "Family Night Club" get-together at the bowling alley at least once a week. My Sim's dad gets angry when she beats him at bowling! xD. Anyhow, this pack is great for my style of play, but it might not be a great pick for people who play the game differently than I do.

I also love the Moschino Stuff Pack because it added a new freelance fashion photographer career. As far as I know this is the only Stuff Pack that includes a new career (I'll have to double-check on that).

As far as which one you pick I don't think there are any wrong choices here. I think it's just a matter of researching your options, maybe watch the game=play trailers in Origin, and pick one that looks like it best matches your style of play. I am very happy with all of the Stuff Packs I own. :D

• If I had to pick one stuff pack it may be Vintage Glamour mainly for the butler, if a family can afford one. It also has some great BB items.
• I thought I would hate Laundry Day, but I don't, and it adds a great realism and pushback. Plus it has really cool BB and clothing items.
• Tiny Living has the ability to make a Micro Home, which is amazingly helpful for a 'starting out' sim for building skills quickly. (It has several exceleration perk options for those that live there.) It also has nice BB items.
• Movie Hangout has a popcorn maker who's popcorn does not spoil, very helpful for snacking, especially with toddlers since they can grab a serving themselves. It has great BB items also, much like those in Laundry day - rather 'boho'.
• Cool Kitchen was worth purchasing to me simply for the ice cream maker. Drag the prepared ice cream to the refrigerator and all sims LOVE grabbing a serving. If you have tough to address weight issues beginning on the lot (roommates, children, toddlers, or your sims), @PugLove888 enlightened me that if you prepare the “Taste of Diet” ice cream. After a Sim eats 2-3 servings of this ice cream they will lose weight.
• Luxury Party is worth purchasing if you have social sims that will be throwing dinner parties, which I find to be a royal pain and I normally avoid like the plague in my game. But... if you have this pack there are a couple of tables that you can just click and food will spawn - one or more dishes. You can even prepare food yourself and add it to one of the tables. It makes a romantic dinner or dinner party work like a charm. Another think what works nicely for a romantic dinner or dinner party is to add a violin or piano and click on it when your clicking on the table to spawn food... and choose to hire someone to play the instrument. You will now also have a lovely atmosphere for the party or romantic dinner.

@Carpincho54, I see that @SheriGR gave the perfect example of what I was talking about... I don't care for the Laundry gameplay in Laundry Day (except for the wash tub & clothes line for off the grid lots, or to make my houses feel more like the old-fashioned houses that existed before electricity).  However, I still enjoy this pack a lot because I love all the furniture, décor items, and clothing! ❤️

And thank you @RandomBuzziness for mentioning the bowling pack.  I love the clothing in this pack and bowling is a fun activity for groups to do. I keep forgetting to make a bowling club, though! 🤭  I don' t  know if @Carpincho54 has the Get Together EP yet, but if so then this would be a good purchase. 

And like @SheriGR , I hate throwing parties in the game, but I still love the Luxury Part SP because I love the formal wear and the makeup that came with this pack!  

@RandomBuzziness, I'm pretty sure you are right with Moschino Stuff being the only SP to have a career! 🙂  The closest we will get with that is when Nifty Knitting will come out as you can make money with the online Plopsy feature so your Sims can have a crafting career, of sorts.  But that is still not the same as an actual career like Moschino Stuff has! 

@Carpincho54, I have found that in every pack there are items that I love, but maybe that is just me.😃   My least used Stuff Pack is Spooky Stuff.  But there is a pair of sparkly tights that I use with almost every formal outfit for female Sims! ❤️  I also love the children's costumes.  I would just watch the pack trailers like @RandomBuzziness  suggested, or go to the link that @SheriGR suggested in order to make a more informed choice! 🙌
