Worst Expansion Pack

I chose thinking of the most unused EP for me not the worst EP.
So Get Together gets my vote.

Windenburg is pretty though I've only had Sims live there once.
Something about the layout just doesn't appeal to me.

The club system is great but I never use it (My Sims aren't allowed friends, outside of family, due to the constant, annoying invitation pop ups).
Maybe it makes the game "more real" for some people. It breaks immersion for me.
