Prettacy: Starting with a very ugly Sim, then trying to make the prettiest Sim possible in 10 generations. Perfect genetics: The founder must have an extraordinary hair and eye color like a Sims with white and pink hair with neon green eyes, and each following heir(ess) must have the founder's genes. Patriarch legacy: The founder and all heirs must be males. Matriarch legacy: The founder and all heirs must be females. Immortal: Keeping the founder alive while his/her family goes on for 10 generations, using the Life Fruit, Death Flowers and Ambrosia. The first generation would only have 1 child, the second generation would have 2 children, the third generation would have 3 children, etc. Genacy: The number of children born each generation reflects which generation the family is in. Fatacy: The founder, all heirs, and all spouses, must be fat. Dominant/Recessive genes: Starting with a Sim who has totally dominant genes like a Sim with black hair and brown eyes, and seeing how long it takes for a totally recessive baby to be born like a Sim with red hair and gray eyes.
Cleanacy: Making it so the founder and every heir have 10 personality points in the neatness category/have the neat trait. The first generation names start with an "A" like Alice, the second generation names with a "B" like Bob, the third generation names with a "C" like Charlie, and so on until the 26th generation names start with a "Z". Alphabet legacy: Naming the children in alphabetical order for 26 generations. Adoptacy: Sims cannot be born to the family, only adopted.
There are many variations to the legacy challenge. The townie rule is different in The Sims 3, because everybody is from the same neighborhood. Every generation there is supposed to be an heir who keeps the legacy going. The use of cheats and who the family members can marry are strictly regulated. The player starts with one adult Sim by themselves in what is known as a "legacy lot" (a lot, usually 50x50 or 60x50, with only the bare necessities for the Sim). A legacy challenge is a challenge created by Pinstar that challenges a player to play a family through 10 generations.
