Wow! such a hard choice for favorite. I was there for the beginning of each and every EP and drooling over the prospect. Except for the Showtime EP. Wasn't that big into the show thing. Since that time, however, after doing some research, I came to realize that I use so many things that came with Showtime that I just don't think I could do without it.
But definitely, the one I use the most is World Adventures. Love going on those quests and I still haven't completed them all.
Next would be Seasons. I just love the thunderstorms and snow. And the festivals!
Last fav - Island Paradise. We finally got to use watercraft! From the rowboats to the houseboats, it was the most awesome new thing my sim got to experience. And the diving is beautiful. If you don't like (or more like can't play) the world due to lag, then just put dive lots and watercraft in other worlds. Still very enjoyable.
The one I use the least - got to say Into the Future. Haven't been in a while. But still, I'm glad I got it.
I've spent so much on this game but I just don't regret it. It's been the most fun I've had since I discovered Sims 1. Not to say 2 and 4 are not fun. I play them too. But 3 just has a special place in my heart.
