1. Create a sim. This sim will be the sim the legacy starts with.
2. You can give them any traits you want. Just remember, the traits you give them will play a part in what wishes they get.
3. Choose whatever lifetime wish you want. You must complete this lifetime wish sometime in the sim's life.
4. Move into any house you want, and start fulfilling wishes!
Rules:
1. You must fulfill all wishes that your sim has until the heir of the next generation becomes a young adult.
2. Unlike the wishacy legacy, you can have your sims do whatever they want, but you also must fulfill all wishes.
3. If there is no more room for any more wishes to be promised, then you don't have to do the newer wishes until a space opens up.
4. Sometimes, your sim will get "impossible" wishes. Examples of this are moving in with a sim you already moved in with, or marrying a sim you already married. You don't have to do these wishes.
5. As soon as the child you chose to be heir becomes a young adult, you can stop fulfilling wishes for your previous sim and start fulfilling wishes for the new heir.
6. If your sim hasn't completed their lifetime wish by the time the next heir becomes a young adult, you'll have to work on that sim's lifetime wish, as well as the wishes for the current heir.
7. No cheats.
8. You must try and complete the promised wishes in a timely manner. No holding wishes until the next heir becomes a young adult.
Have fun! Also, feel free to share pics and things like that on this thread.
