This is, honestly, my third favorite pack (#1 being Cats & Dogs, and #2 being Seasons). I just love the new world of Sulani. There are so many gorgeous hairstyles and outfits in CAS. There are lots more activities to do. Being able to build over water is really fun as well. My all-time favorite part of this pack is the mermaids. They are amazing. I love them so much and they make things more interesting and fun. I still haven't explored everything from this pack. I am still working on the Conservationist career and restoring Mua Pel'am.
I have two problems with this pack:
#1 Every activity like swimming, snorkeling, and aqua-jetting all build fitness skill. There is no separate snorkeling skill or even freediving skill. I was kind of hoping that they would be more separated. If you have mermaids, your fitness skill will increase quickly.
#2 When you free dive, you don't get to see them underwater. All you see is them diving and then they come back up to the surface. I was really hoping that there would be some underwater section like in The Sims 3, but I totally get why they didn't do this. It probably would have made it so you needed a lot of computer power to run this pack.
