Well a stuff pack is more so a pack to add more stuff, ie Cas and BB items, to your game. And they have done a great job doing that. I prefer the stuff packs to keep the look of my sims and their houses updated without having to use CC, so for
me it has been money worth spending and it’s been over time so it’s not that noticeable.
Each stuff pack also tends to add 1 or 2 small game play feature(s) as well which is a nice touch. I prefer stuff and game packs with this iteration over most of the EP’s to be honest.
