Yeah, it doesn't look like a game pack. Some GPs came with a new world even, and ones that didn't, offered quite a lot of new activities and mechanics.
But after a closer look I was impressed with amount of BB that comes with it, definitely more than we usually get in a SP. So, this pack is more like a two stuff packs for a price of two stuff packs. Still only stuff and I'm not sure how I feel about it, but I've bought expansions on sale purely for BB and CAS, so who am I to judge haha.
