I love the Sims 2 (console) biodome! It was my favourite and I still dream about it LOL.
Brazilian, Australian or Caribbean inspired with the idea of the great barrier reef for scuba diving lots, houseboats or a mock houseboat/yacht lot. If Caribbean inspired maybe a Zombie life state (even if temporary) from Haitian inspired culture :)
edit: and I'd love some old Sims 2 attire, guilty of loving that tacky fox shawl with mini dress. I miss the Sims 2 Fisherspooner's "Just Let Go" Simlish version song XD And the Fashion Model career from Sims 2 console, add this to base game!
