It looks like MacOs X versions are separately outsourced to As Pyr. (Actually, As Pyr publishes them, and others may do the development.)

v2 is more full-3D. And Sims have new experiences unavailable in The Sims, such as aging and eventual death. Sims can become pregnant and produce babies that take on genetic characteristics of their parents, such as eye color, hair color and personality traits. Genetics play a major role in the game, and as such, dominant and recessive genes play a larger role than they did in the original game. Additionally, babies in The Sims 2 progress through life stages to become adults, while babies in The Sims only become children before ceasing to continue aging. The aspiration system (described above) is also new to The Sims 2.
