Well to be honest I feel that ever since Sims 4 they really have held back on content enough to make almost every pack feel a bit unsatisfying. Like there were obvious missed opportunities. So yeah depending on what level this pack concept was made into it would likely have less than what would be fairly expected.
I have given it a lot of thought and what I came up with is that no matter what the concept of any pack was, if they made a pack that had more stuff than a Game Pack but less than an Expansion, and they charged slightly more for the Game Pack but the concept was thorough and play testing was good, I doubt the fans would be too upset about a subtle price variance if they felt they got their money's worth. Same would go for a concept that was bigger than a Stuff Pack but less than a Game Pack. It won't be true for all fans who are never satisfied though. Also EA never got the memo on under promising and over delivering.
I think how you would tell if you got your monies worth is that when you play it through and you think to yourself what would you have added, or how would you have done to make it better and you couldn't think of anything substantial. That's how you'd know you got you monies worth. Especially if the play through was clean and with no real game glitches.
