The Sims 2 boosted the graphics to a fully 3D world. You could follow your Sim from the cradle to the grave, as it introduced aging, and community lots were now part of the world. Improvements to CAS meant that the Sim’s skin tone and size was now fixed, and clothes and hairstyles could be changed without impacting these. And, although is was still not possible to wander around the neighbourhood, Sims could eventually see their neighbours, making the world look more populated. Each lot was still it’s own save game without impact on the others, meaning that your Sim’s great granddaughter could bring home the same Sims from school as previous generations.
