that sounds waaaay too much like making what should be long term goals that take maybe even years to complete into easy short term goals...
We're not trying to make them super easy, just actually doable in some cases (like finishing plushie/beanbag/etc collections). With the hunger suggestion, it's something we'd have to make sure it wouldn't be for too long/too quick/too easy (that's why it's something we have to play around with if we go that route).
I understand, it's just a not so fine line and there's been instances on both sides of it. The random game spits out 10k almost as often as not nowadays... Goals can always be made easier to achieve but once they are its not the same if they're made harder as they're already neither exclusive nor impressive. As someone who desperately misses the "% users have this achievement" stat from the achievements page, I like it when some are very hard to get, it makes the game worth playing really.
