Re: which pack to buy
They're super different. I'd say City Living is the better pack, but it depends what you want. As someone who really likes to build, I find City Living isn't great for that because of the number of apartments and the constraints that come with that. I love building beach houses in Island Living. But City Living has really good gameplay, with festivals and apartments (both cheap, dirty ones as well as expensive, fancy ones). But then Island Living has mermaids and you can talk to dolphins, if you're into that.
