Although The Sims 3 base game came out with only a single world (Sunset Valley), the very first expansion pack would really showcase the flexibility of the new open world game design. Without a doubt The Sims 3 was the most diverse game from the franchise when it comes to actual real-world representation. The Sims 3 World Adventures broke boundaries They were quite vague reflections of actual places in the real world. It added more distinct worlds resembling ‘Far East’, Tropical and Mountain Destinations. With additional expansion packs more worlds were added including The Sims 2 Bon Voyage. For 2004 this was a groundbreaking addition and really redefined the sandbox genre. Whilst we had three different worlds to pick from we also got the ability to add custom worlds based on a variety of provided world maps.
