The Sims 2 is set some 25 years after the original game. For instance, the Goth family has aged significantly with Bella Goth mysteriously vanishing ("dying") at some point in the 25 years. Because the entire game has progressed from 2D sprites to 3D models, all content in The Sims 2 had to be created from the ground up. Due to this, The Sims 2 was not made backward-compatible with any content from the first generation of the main series; however, some objects and features from the original series were remade for the sequel.
