And consider the sheer numbers involved in completing the sticker collection. For Grimsborough alone it's 2404 stickers. With 5 stickers a pack that's 480 packs (in the statistically possible, but highly unlikely case you all get different stickers), equalling 1440 stars needed (playing in normal difficulty). And those 1440 stars can only come from the 9 stars left after wrapping up a case,  meaning you'd need to fully complete 160 cases (are there that many?)

Not to mention that you'll run into duplicates rather quickly, so completing the collection might require multiple times that number. And duplicates are practically worthless. A hundred of those (and you need 100, 99 will get you nothing) will get you ONE pack in return,  with the possibility, oh irony, of all those being duplicates again.
