I'm in my 5th decade, female, and I voted that I dislike the GP. But for me, my dislike isn't just because I don't like the idea of the pack.
I remember seeing Star Wars A New Hope when it first came out in theaters. Wow, it was a blast. Movies 4-6 are my absolute favorite. I didn't like the prequels (Anakin REALLY got on my nerves), and I just haven't been able to get into 7-9 (honestly, I like the "canon" book series that came out in the 80's-90's where Han & Leia had twins Jaina & Jacen). I also really like everything that I've seen of Galaxy's Edge at Disneyland & Disney World and hope to someday go there in person. So if Sims 4 was at a state that I could really enjoy, I'd be all over this pack.
But that's the problem, and the reason why I voted that I dislike the GP. I feel like there's quite a few things with the core game that still need to be addressed. Like babies as objects, screwed up emotions system, the mobile game gets bunkbeds but we don't, game breaking bugs, etc & so on. I've reached a level where I'm just completely frustrated and dissatisfied, and just not being heard. And because of that, I'm just not interested in buying this pack, or anything else they release.
