Which pack should I get next?

Vampires is my favourite pack and for any supernatural/vampire fan like myself I definitely recommend it. The vampires are the best we've ever had in my opinion and so versatile and fun to play. Laundry Day would probably be my second choice since for me it is my favourite SP so far and one I use a lot (and this is coming from someone who didn't vote for the laundry theme). It's a big SP with lots of nice CAS and build objects and gameplay value. There is something really relaxing about watching my sim do their laundry and I think it is a great pack for family style players. I do like Jungle Adventure, particularly some of the build objects, but I don't use it as often since the jungle doesn't really suit many of my sim characters. My First Pet is probably my least favourite SP as I hardly ever use it, although the hamster is cute. It really depends on your own play style though which pack will appeal to you the most. I suggest checking out some reviews and SimsVIP guides if you haven't already.
