I think the boredom comes from the fact that the games are created with such few features that they are easily explored. I feel the boredom too!
I just bought the last pack Magic Realm, and I don't know why I buy, but I belive its the hope that they will come to their senses and finaly make a pack worth playing. (I have played since the sims deluxe)
It feels like the sims has becomed a cash cow, and dividing the games into GP, EP and SP is just an excuse.
So I feel your frustration and boredom, but I really hope they start hearing what people want, instead of producing products that in the end ruins the feeling that playing the game gave before!
