Which packs did you deactivate/uninstall?

All of them, use them all fairly equally, deactivated none, no regrets.

I own all the expansions and game packs (well besides Realm of Magic as it isn't out yet) and most stuff packs. I hadn't uninstalled any yet but if taking pictures is going to cause more problems, I might have to uninstall the maschino stuff pack until it is at least fixed as I had force my game to shut down and that is a problem. That is the only regret I have as I got it just for that and it is still broken. Doesn't matter if they fix approved pictures if you can't even take them.

I own all, and I use all.

I own them all and I use them all. They all add something to the game that I like.

i own all except island living and moschino, and i use all of them.
the only thing i wish i could uninstall is the new ugly menu and loading screen.

I have a tiny bit of regret for buying Seasons, but not very much regret. I love all the packs.

The packs I would consider to be deactivated would be those I haven't purchased. :)

I never deactivate packs. However, my least used pack is MFPS in terms of build/buy and vampires in terms of gameplay (love the b&b though).

I don't uninstall anything because there is always some small things i use from every pack since well I have it so why not

that being said I also don't buy everything at least for now because i know my old and slow computer will hit its limit at some point and i need keep some space for my fave themes that have yet to release for most part

use most?
probably vampires since i love occult
though i also could not play the game without seasons since i hate sunshine just as much as my vampire sims

regret buying?
Get to Work if anything
I do use loads of cas and b/b from it and well I needed aliens but I honestly hardly ever do the careers or retail because it just got kinda boring after some time

I use them all... if I don't have any interest in a pack, I simply don't buy it (which is why 'My First Pet' still remains to be the ONLY Sims pack I have never purchased).

Even if I don't particularly care for a specific pack that I do own, I don't see a reason to uninstall it... I mean, I paid money for all the packs I have. It would be a waste to simply not use one just because I don't care for it. Plus, there's always at least something in each pack I actually do like. Even if it's such a small thing. For example, 'Outdoor Retreat' is, in my opinion, the worst game pack... however, I actually do like some content it came with (like the campfires, horseshoe pit, and coolers). So, at least the pack isn't completely going to waste.
