Thanks to Valley dos Sims for the tip!
While you could certainly make an argument that EA is nickel-and-diming customers with constant Sims 3 expansion packs, they’ve typically been meaty additions that add interesting gameplay to the Sims experience. The Sims 3 Generations, unfortunately, adds a lot of content, but not a lot of substance.
Generations focuses on adding elements to every stage of a sim’s life, with an emphasis on children and teenagers. A lot of these additions are really interesting, like how adults can now suffer a midlife crisis, during which they have particularly childish wishes that cannot be canceled (though you don’t have to accept them).
One particularly clever feature is that infants can grow up with an imaginary friend that no one else can interact with, which can be turned into a real creature later in life. Teens and young adults get a lot more options in terms of relationships, including the ability to go on dates and host parties (especially when the parents are away), as well as go to dances. In what may be true to life, your sims can be ditched or denied at events like prom night.
