What are your two favourite EPs?

Seasons is both my favourite and the EP I use the most. There are no activities in particular that I enjoy more than those from other packs (although I really like the customisable holidays), it's just having seasons and weather in general that makes the game feel more alive and complete. And with every world having its own climate, the only way not to use the features from the pack would be to uninstall it, but I can't even imagine playing without it nowadays.

Second would be Cottage Living. Ever since I bought it, I've been using at least some of its features (be it the farm animals, the Simple Living lot trait or just the furniture) in most of my played households.
