I recently started a "challenge" where I'm following "one sim" through all the game generations.
If you're interested in doing the challenge, basically all you have to do is create a sim with a similar personality, appearance and of course name and basically live their lives in the Sims 1, the Sims 2, the Sims 3, and the Sims 4.
The only difference is they have to do something different career/social/family wise.
So. . . it's almost like your sim is saying "In another life I was an Acrobat" or "In Another life I had thirteen children" or "In Another life I died in a fire" - possibilities are endless.
For my go at this - - - in the Sims 2 I plopped Timberly down in Belladonna Cove. Check out episode one if interested - her Land Lady takes a liking to her.
