I feel like talking about EPs today, let's do an (almost) full ranking here.
I read a lot of undeserved hate about some EPs up there. If only they knew all features they have, and not just the "main" one.

(Well, it's understandable since with the Ultimate Collection we got everything together.)

Top 1: I only played apartments once and don't really remember how they work, but my top 1 is still
Apartment Life.
-
Witches: they are the best, I just love them. I don't want to type 4 paragraphs about how much I love them, so let's continue.

-
Furniture: don't ask me why but I just love the furniture??? The wall closet, that TV with shelves, that simple square coffe table, that modern library, the classic modular sofa, the socialite objects (gearhead ones are ugly though, I have to admit).
And other, but still very good, stuff:
- A lot of architecture items
- Ability to move wall objects up and down
- The playground set
- Spiral stairs
- The 3×3 aquarium
- The heater
- The cabinet with mirror with the new interactions for the sink.
And probably a lot of stuff I'm forgetting. It just added a lot of things the game needed. Well, enough of AL.

Top 2:
Open for Business.
I probably like it as much as AL, but honestly, OfB alone wouldn't be really good, it needs the other EPs to have all its potential. 2nd place it is.
Well, the obvious feature,
running your own business. What makes it so good is the variety you can have:
- You can simply buy from catalog.
- Or sell what you craft from the 3 stations or the 2 ones that came with FT (sewing and pottery).
- Run a barber shop.
- Run a restaurant (one of the few things I still didn't try, but it really sounds fun).
- Sell cooked food directly.
- Sell the fruits and vegetables you grow.
- Have a witch with a potion shop.
- Run a car shop.
- Or a pet shop.
- You can even just simply put a ticket machine in your house and it will be profitable (if you are willing to have half of the hood walking around home freely

).
And then there are mods that add even more kinds of business. Massage shops, pharmacies, chocolate shops...
-
The 3 crafting stations are still very good even if not used for a business. The snapdragons make life so easy... I love Servos, they are a nice addition to any family. And the toys are so fun, specially the evil versions.
- Some
business perks are really useful even outside your business.
- There isn't a lot of furniture, but I like the Mission set.

The windows and doors too.
- And the bathroom towels. It doesn't look important but I like it, specially because when OfB was released, K&B Stuff Pack didn't exist yet.
I think that's it about OfB?

Top 3: I guess my top 3 would be
Bon Voyage.
Honestly, I don't send my sims often on vacation, but there's still a lot of cool things in this EP: massages, learning teleportation, having Bigfoot in your family, the pirate ship, the rolling log, the sauna...
And the
beach lots, of course. Great addition to the Seasons EP.
And the
jewelry, probably the best CAS addition from all EPs.
Plus a lot of good
furniture and
clothes, and architecture objects. There's no way I can dislike this EP even if traveling isn't that fun for me.

Top 4 goes to
Seasons.
The seasons themselves and the weather can be really annoying sometimes, but that won't stop me from putting Seasons in top 4, as you can easily control all that with the weather machine.

Even though, I still like seeing
snow. And with the Holiday SP, it's almost a must.
Gardening is tiring, but I really like it. Being a Plant Sim makes it much easier. I use them as full time gardeners and then sell the vegetables and fruits to all the hood. The
juices you can make with them have nice effects, or you can put them in the fridge for the shiny food.
And then, the kitchen deco, just like the bath deco from OfB, it was very needed.
Also the hot chocolate machine, I don't know, I just love it.
And let's not forget the
careers. This is one of the only 3 EPs that add careers, and I love career rewards.

Top 5:
Free Time.
I have to agree that the hobbies are annoying. Those messages telling you your sim is losing enthusiasm in X hobby appear too often, and the sims inviting you to the hobby lots too. And I also dislike how unbalanced the hobbies are. It's easy to accidentally max the enthusiasm for Arts and Crafts, but if you want to do it in Science... Prepare your sim for nights of looking through the telescope.
Now, the
aspiration benefits are really good and I couldn't live without them. The
Best Friends Forever thing too.
It also came with many
careers and so many new
objects: a new set for kitchen, baby and children objects, pottery, sewing, the model train, the lemonade stand, the ant farm, the soccer goal, the basketball court, the restorable car...
And the many new
interactions, some of them exclusive depending on the sim's enthusiasm. But not all of them. Catching all bugs is still something I want to do.
It also added more variety to the
sim's wants, with both the secondary aspiration and the hobby related wishes.
And I almost forgot the Genie came with this EP.
Well, I can't dislike this EP no matter how annoying the hobbies are. There's just so many new cool stuff. And there are hacks to make hobbies less annoying after all.

Top 6, near the bottom, will be
Nightlife.
Honestly, I would most likely choose this EP if I needed to remove one, but I'm trying to be a bit objective here, it doesn't deserve being at the bottom.
Personally, I don't really like
restaurants,
discos, or well, the downtown in general. But I can't deny they are a good addition to the game.
The chemistry is something I can live without, but the
dates are nice. I like my couples to keep the letters or roses from before they were married.
About the
vampires, well, they are not bad but they are my least favourite life state. I hate that they lose their needs so fast even if they are inside home, without windows and in the basement.

They can't do much, you basically need to have them sleeping 13 hours of day. It's also annoying that they can't work properly (without mods). Well, at least there's OfB for that.

Cars are nice, but my fav car is the restorable one from Free Time, so...
I like most of the furniture and clothes, and it has some great objects like the wall TV, the photo booth, the fire jet, or the bowling alley.
My 2 least fav ones: I'm sorry but I can't choose the order for the last 2. They both have good parts.
-
University: There's nothing I dislike from it. Most of my sims go to uni. As much as I like the
careers, the
university life and the benefits from going to it, I can't put this EP any higher, because it doesn't have much more to say about it. Well, I like the fountains, the mini fridge, some of the medieval furniture, it also came with some instruments and exercise machines, but that's it. Well, and the bubble blower.
I never played a zombie, but they don't look as unique as the other life states. (Besides, zombies were re-added in FT and AL).
Understandable from the very first EP, but I'm sorry, you needed more content.
-
Pets: I read so much hate to this EP and I don't like continuing it, but there really aren't enough reasons to put it higher.
Pets can be annoying. They are very good company to single sims, but having them in bigger families is just one extra thing to worry about and they don't really contribute to the family. I don't often have pets. The
womrats and parrots are nice, though. They don't need as much attention as cats and dogs, and parrots are a more fun way of skilling charisma.
Let's be honest here, I love
werewolves. I would put this EP at the bottom with no doubt if it wasn't for them.
The futuristic looking furniture doesn't look bad, but that's it, there isn't a lot of new items.
I have yet to try having a pet shop, may be fun.

And for
Stuff Packs...
Top 1 would be Mansion & Garden. I love the climbing ivies and the other plants. I don't really like the Second Empire set, but well, it's there.
It added the tool to adjust roof angle, it was possible before, but with cheats, it was harder.
The solar panels and windmill are really good so you can stop worrying about the bills.

Then it added the ceiling fans, the lake fountain, and also some hairs and clothes that are pretty good.
But the best feature of M&G is definitely the quarter tile placement cheat. I can't live without it.

It added so many things, definitely the best SP.
If we count M&G as an EP... Then my fav would be either Holiday or Kitchen & Bath. I like all the Christmas stuff. And the objects, walls and floors for kitchens and baths were really necessary.
My least fav is Family Fun. Sorry for it, but I don't like the furniture.
