I mostly bought city living for apartments, so technically to have more room for my Sims.
I do like the flea market, and I do like the apartments, but I wish we had access to the entire thing, except for a couple rooms in each one.
I also like some of the clothes, and having the expansion itself.
A while back they had a free trial to City Living, but it was only for a little while.
I try to get all the packs on sale as well, so if I I love the pack, or mixed on a pack, it wasn't a huge amount.
