The thing is... I absolutely detested whatsitsname? The vacation thing from Sims 3.
Tomb puzzles... I just bought Tomb Raider Underworld for $0.80 on Steam on a sale. It costs $2 normally. I daresay Tomb Raider does Tomb Raiding better than Sims.
I never played Castaway, I had left Sims 2 behind at that point.
I tend to find "spending time away from home" in Sims games disappointing and annoying at best, boring and frustrating at worst. I hated the vacation pack for Sims 1, as well.
As for the culture part... Meh. Well the dance styles look mildly interesting. And the skeleton? No thank you. I want a proper Servo, please.
