Well, it adds so much new things. One of the best expansion packs yet.

Well, i was quite surprised when i start to play. It's really a kickass expansion. Adds so much new things, you almost can't count them. Decoration objects are so cool, it's so much of them, and i swear i didn't even dare to try adding all of them. Really awesome. From farming to modern, for children to kitchen stuff > (IMO the best). Weather is very nice balanced. (you can always change that if you wish) then, farming, awesome, did just saw how it works. really outstanding and fresh. Harvesting fruit, what could possibly go better?! Making snowmen in snow? Or whatching that your sim wouldn't freeze outside or be burnt because of the sun? It's your decide. IMO really great.
What surprised me, are those sounds. I know you already know music is one of the best. Every x-pack, new music. Sweet! But not only that. What surprised me really, was the sounds from nature. Yes, you heard right. When there is winter, there is wind blowing really hard, snow falling, and believe or not, it feels just right. Then when rain falls, those STORMS. Really loud. Great, and hearing a rain.
Yes, and this is not all. All other, but even just that it's great. Really, worth every dollar you give!
