OFB. Seasons and Nightlife are good too. I have all packs in my Origin

I can't choose at all, they are all so good

This is so tough. I havent played sims 2 in many many years but i recall getting the most enjoyment from Seasons i guess.

Compare this to Sims 3 EPs though, i could EASILY do a ranking from best to worst EPs, considering half were garbage. All of the Sims 2 ones were so iconic.

The trinity is Seasons, Nightlife + Open for Business
