Released on 21 June 2019, The Sims 4: Island Living expansion pack whisks your Sims away to Sulani, a sun-drenched Polynesian-inspired paradise filled with ocean fun, vibrant community, and a brand-new occult life state: mermaids. Whether you want to relax on the beach, care for the environment, or embrace magical sea powers — this pack has it all.

🧠 Final Thoughts
If you’re a storyteller, builder, or life simmer, Island Living adds depth and immersion. The world of Sulani is not only visually stunning but responsive — your actions change the ecosystem, unlock secrets, and create a living, breathing community.
Mermaids, environmental gameplay, and the unique pace of island life make this expansion stand out. While it’s lighter on goal-based play than others, its beauty and charm more than make up for it.
