Legacy challenge

A legacy challenge is a challenge that starts with one adult sim by themselves in what is known as a "legacy lot" (a lot, usually 5x5 or 6x5, with only the bare necessities for the sim). There are no cheats allowed (except for move_objects on/off to fix a bugged game or to decorate). That sim has to marry one of the townies or an NPC and have children with them, and pick a child to do that same thing. This is called "carrying on the bloodline". This continues on for at least 10 generations. Every generation there is supposed to be an heir who keeps the legacy going. The townie rule is different in The Sims 3, because everybody is from the same neighbourhood.

Some Types of Legacies

 * Uglacy: Trying to create the ugliest sim possible in 10 generations.
 * Prettacy: Starting with a very ugly sim, then trying to make the prettiest sim possible in 10 generations.
 * Alphabet Legacy: Naming the children in alphabetical order for 26 generations. (e.g. generation 1's names start with 'A', generation 2's start with 'B', generation 3's start with 'C', etc.)
 * Matriarch Legacy: Starting with an adult female, and getting her pregnant WITHOUT having her get married. This goes for all generations.
 * Riskacy: Having the founder and heirs marry the first adult sim of the opposite gender (playable, townie, or NPC) that walks on the lot.
 * Cleanacy: Making it so the founder and every heir have a 10 personality of neatness. Or have the neat trait.

These are just some of the many different legacies that there are.
