Outdoor Retreat or Jungle Adventure?

They each have their strong points, but OR is very tame and limited by comparison with JA, so if I had to choose one, JA would be my first choice without hesitation. However, as @bshag4lv says, the two packs go together really well. I was not interested in OR when it first came out, but ended up getting it after I already had JA, because I really wanted all the camping stuff to use in the jungle and having it has certainly enhanced my gameplay (I suppose that makes JA the most expensive game pack I have bought so far :p but I am loving it). So you could always keep OR as possible option for the future, when you eventually have the means to buy it.
