OFF THE GRID Gameplay ideas [graphic]

If you don't own Vampires, you can't make a Vampire Clan with the clubs from Get together.
Get Famous lets you get famous by being an awesome Vet, right?
two packs can be combined, and they do it here more than on any other Sims game so far.
there was the totem in Sims 3 that spawned in the world if you had Seasons and Supernatural installed that allowed Occults to summon special whether you couldn't get otherwise. And I really like that.
I don't see how it makes sense to exclude stuff just because it would require two packs. Why not just hide it if the requirements are not met?
