Just like in the corresponding GP thread, here comes my entirely subjective ranking of the EPs. If I were to rank these packs objectively (assigning more priority to things like novelty, uniqueness, bugs, and overall playability), the list would look a little different. But I decided to focus on my personal preferences and how much I need each pack for my gameplay. There is one EP I don't own and can't rate (but not because I don't own it). I'll explain at the end of the list.
14. City Living
Apartments that we can't build ourselves, festivals that can't be edited, Asian names for everyone regardless of ethnicity, too much focus on the world with no gameplay elsewhere. Can't understand the hype around this one.
13. Get Together
An uninspired stew of features that don't fit anywhere else. Club system annoyingly underdeveloped for being the only real gameplay feature. Tries to use big world to compensate for lack of depth.
12. Island Living
Like City Living, too much focus on the world, nothing to do outside of it. At least it's pretty.
11. Cats & Dogs
All style, no substance. Could spend all day mixing breeds and dressing pets in CAS, but gameplay is very lacking. Cats especially can't do anything.
10. Discover University
Extremely repetitive and grindy, no fun at all for rotational players like me who don't like being stuck with one household for weeks just because sims will fail university otherwise.
09. Get Famous
One of the best packs when it comes to gameplay over looks, and becoming a celebrity is a challenging task for once. It's just that I don't care much about celebrities both in real life and in the game.
08. Horse Ranch
Cool because I like horses, but offers very little for its price. Making a full-blown EP just about horses, but with rabbit hole competitions and no real unicorns, no idea know whose stupid idea that was. Would rank a lot higher if combined with Cats & Dogs, or as a standalone GP.
07. Get To Work
Unpopular opinion, but I really like this one. The active careers are fun and I wish we had more of them. A shame Sixam isn't residential, would have preferred a bigger alien world over the bad joke that is Magnolia Promenade.
06. High School Years
Basically Get To Work for teenagers. Finally, something to make that lifestage more unique and compelling. Yes, it's repetitive, but so is everything in this game (not to mention school in real life).
05. Eco Lifestyle
Much better than its first impression once you learn how to handle the annoying aspects. Don't like Evergreen Harbor, but unlike some other packs on this list, this one doesn't force me to live in its world to make use of its features.
04. Snowy Escape
Another pack with too much focus on its world, but in this case I'm biased because I love the world and its activities, so it gets a pass from me.
03. For Rent
What City Living should have been. Finally a pack that lets us build apartments and play as the landlord. That's all I wanted, I barely care or even know about the pack's other features.
02. Cottage Living
Love everything about this pack, but especially the farm animals and the very realistic Simple Living lot trait. As much as I try, I can't think of anything to dislike.
01. Seasons
The sim world just doesn't feel real or complete without it.
Unable to rate: Growing Together
Creating an EP out of so many features that should have been base game makes this the rudest cash grab ever. Love the features, hate that they're hidden behind a paywall, so I can't rate this one fairly against the others.
