The Sims 2, commonly referred to as TS2, is the sequel to The Sims. Released in September 2004, it heralded sweeping changes from the original: most notably, the isometric view of the original had given way to full 3D. Also, Sims now have life stages (Baby, Toddler, Child, Teen, Adult and Elder) which had them age from birth to death, and their genetics would be passed on to their children. Unlike the original Sims, where you could spend forever raising their skills, the aging system in The Sims 2 imposes a time limit on this before your Sims die. The main aim of the game is to lead a Sim from the start of life to death. Sims will need to build up skills and relationships with other Sims, so that he/she can be successful in their career. A player will also need to make sure a Sim is happy and well by fulfilling wants (including lifetime wants, avoiding fears, and fulfilling motives. Sims' personalities are also given an overhaul with each Sim having an Aspiration, Wants, and Fears. The Sims 2 shipped with 3 premade neighborhoods. Pleasantview is a continuation of the original Sims storyline 25 years later. The new neighborhoods are Strangetown, a desert landscape with paranormal occurrences, and Veronaville, which is based on several plays by William Shakespeare.
