Eco living was a stuff pack. I realize that there's no actual protocol and technical limitation in what can and cannot be exclusive to gamepack or an expansion pack, so they can pretty much put anything out and either label as "expansion pack" or "stuff pack" and sometimes give/make an illusion that those things are somehow different, but in reality they aren't. We have seen the releases of gameplay mechanics (dine out restaurants, get together club), worlds (midnight hollow and winderburg), and even mechanics (parenting and careers) in both packs: expansion and game packs. So what we know, they can either university either in a game pack or expansion pack which wouldn't matter at all, but probably would sell better with a 40$ If it was label as an expansion pack.
