Would you rather have World Packs instead of Stuff Packs?

I think that if you want both a larger world and new stuff to fit its theme, you're going to be paying more for it than what you'd pay for a SP. You'd basically be getting a trimmed down GP.

Would these come with new CAS as well or just a handful of B&B objects? I'm not sure I'd be too excited to see them release a new pack without any CAS or new gameplay features.

I guess I'd rather have them stick to making SP.
