These Rules must be abided by throughout the challenge. Any breaking of these rules will either (a) end your challenge, or (b) incur a fine in points.

1. You must have one sim living on the legacy lot at all times that can trace their ancestry back to the original sim in a direct 'blood-line'. The challenge ends when the blood-line dies out.
2. Legacy Sims - the Heir may only marry Townies or NPC's. Maxis sims (eg. Goths, Newbies, Caliente's) and Player sims (Kumiko Azami) cannot be married or co-habit (i.e. move in). Bella Goth is considered to be a townie, rather than a Maxis sim.
3. Adopted children do not count as legacy heirs. The exception to this is when you know that the heritage of the adopted child is from the original Legacy Sim.
4. In-breeding is not allowed amongst legacy heir sims. If done, it incurs a 2 point penalty or an end to the challenge. The only situation where Sims can interbreed, is if the legacy heir on the lot has died and a direct-line descendant exists off-lot.
5. Aging must be on at all times.
6. The game must be saved on each exit of the lot. i.e. no quit without save after a bad chance card, or an unplanned death.
7. Sims moved out of the Legacy House to the Lot Bin or when they find their own place may NOT return to the legacy house. The exception to this rule is Sims that have gone to University. Sims that have gone to University (if the legacy heir) must return to the legacy lot on leaving Uni.
8. No Cheats (except the 45degree bool prop, and move_object on for purely decorative reasons (and the censor off for personal taste)
9. No Hacks which affect Aspiration, Mood, Money, Influence, skills, Relationship or Birth chances. So e.g. Abduction patch, or Twin patch - No. Less Weeds or Daily Gardener - Yes. The InSeminator is right out! There is a list of allowed and not-allowed hacks further down the list. Please refer to this list before including a hack in your game.
10. No SimPE manipulation of Legacy Sim, or NPC sims, except Sim Surgery (i.e. changing their looks)
11. All the Aspiration and Career Rewards are acceptable to use (i.e yes it is ok to use smart milk, elixir of life, the energizer machine).
12. You can use non-maxis recolors and new mesh objects in your game (as well as walls, floors, terrains, etc, etc.) Just not ones that have been hacked.
13. You can send your Sim to University and there are extra bonuses down below.
14. Aspirations for all Sims born in game, are done by the roll of a dice.  This is done at birth, and if the aspiration changes at Uni. It is not permitted to choose an aspiration yourself unless you've rolled a 6! If you have no dice, then picking a number out of container is ok too. If you've accidentally set an aspiration without dicing - this incurs a 2 point penalty.

• 1: Wealth
• 2: Knowledge
• 3: Family
• 4: Romance
• 5: Popularity
• 6: Pick one yourself

• Remove all hacks from your game, and then add just the ones that are allowed. Check the Hack List for hacks that could be essential for later on when your lot has corruption problems.

These are suggestions only - and will enhance your game play, but it's up to you whether you do them or not.

• (o) The easiest way to control your game so that you don't have non-allowed hacks is to create a separate game just for it. This tutorial will show you how.
• (o) You may create custom townies for your neighbourhood. See this thread for how to do it.
• Creating a new hood without other sims in it, makes it easier for your sim

See this thread for Starting Tips

1. Have you backed up the neighbourhood and/or lot before you started?
2. Have you saved a good picture of your original couple for your Generation 2 gift.
3. Are you about to have a child become a teen? (Remember that aspirations are chosen by the roll of dice).
4. If you have graves or custom paintings... Have you created a sims2pack of the lot which includes the graves and paintings? (This is invaluable for problems with corrupt lots).
5. Your Legacy Heir is getting engaged - Is their partner a townie or NPC?
6. You're moving in a sim into the legacy house - Is the sim a townie or NPC? (special case: player sims with no skills, no money and unemployed can move in for the purposes of getting around a Maxis bug. However if this is done - you must ok it with Kiri first.)

Step 1: Don't Panic Check Various Simmers and MTS2 to see if there's a hack that can rectify the problem.

Step 2:
(If you've backed up the lot) Check your previous back-up. If this lot is ok,lot-bin your corrupt one, and install your previous back-up in your neighbourhood. If things remain ok, you can than delete your corrupt lot.

(If you've backed up the neighbourhood) Save your corrupt neighbourhood, in case you need information from it. Install your backed up neighbourhood and check that it's ok. If it is, then continue on with the backed up one.

Step 3:
You can't use your back-up. PM me.

a. Try Lot-binning the house, and then re-installing it.

b. try sim-binning the family and then re-installing them.

c. If the lot is corrupt, and won't reset:

1. Move the family out of the lot and install them on a new 5x5 lot.
2. Restore their Aspiration and Career Rewards using the Carrigon Collections.
3. You may use Kaching/Motherlode to restore their total value to the closest thousand underneath their pre-corrupt value.
4. Send the corrupt lot to Kiri, and I will attempt to rescue graves and custom paintings.

You will need to rebuild their house on the vacant lot.

Alternatively - Replace step (1) in above list with this:

If you've got a sims2pack of the house with graves and custom paintings. Install this house and bin the saved family, then replace them with the current family.

If No backups are available, and no measures taken above work - then restarting the challenge is all that's left.

Points

1 for each Generation (max 10)

1 point for each $100,000 in net worth the family has (round your current net worth up)

1 point for each PLATINUM grave on the lot

1/3 point for each family friend the family has at the end. (round spare 1/3s down)

1 point every time a sim fulfils an 'impossible' want (a want scoring 30,000 points or more, limit one per sim per want. There are other wants that also count for this, like "have 10 children")

The impossible wants are as follows:

• Family: “Have 10 children” “Have 20 grandchildren” “Send 10 children to college”
• Wealth: “Make $100,000”
• Knowledge: “Max All skills” “Be abducted 10 times” “Have children abducted 10 times”
• Romance: “Have 30 loves at once”
• Popularity: “Have 30 best friends at once”

Do NOT confuse “lifetime wants” with “impossible wants” just because something is a lifetime want, doesn’t mean it’s an impossible one.

-1 point every time a household member drops into aspirational failure, requiring a visit from the sim shrink.

-1 point for each infant, toddler or child that gets taken by the Social Worker

-2 points for every inter-bred birth in the family.

-2 points for each visitor that dies on your lot.

1 point for each group of 10 relatives that are alive in your hood at the end of the game. (That is - aunts, uncles, cousins, grand-parents, great-grand-parents, great-great-etc-parents. To count the relative, they must have the original sim as a great-great-etc-parent.) This challenge was suggested by Pink! They do not however have to be living in the legacy house.

2 points if all 10 career reward objects are on the lot (One time only)

1 point for each different type of NPC that you have children with over the whole legacy.

1 point for each different colour ghost you have on the lot at the end.

1 point for each alien born on the lot (1st generation aliens only, children of aliens don't count, unless it's by abduction)

2 points if the birth that brings in the last generation is twins.

2 points if you can get two social bunnies to have romantic interactions on the lot (One time only)

2 points if the ghosts on your lot can access your sims. (i.e. no blocking off the ghosts from the house by water, etc. Putting the bedrooms on the 2nd floor is allowed though.)

-2 points for each grave that is deleted. You're not supposed to delete graves.

2 points if you manage to collect ALL the different types of ghosts on the lot.

University Points:

Scholarship Bonus Points:
½ a point if a teen earns $9,500 or more in scholarships for collage
1 point if a teen earns $11,000 or more in scholarships for collage
1 ½ points if a teen earns $12,500 or more in scholarships for collage
2 points if a teen earns $14,000 in scholarships.
The teens in question don’t have to be the heir (ess), any Teenager that is part of the household can earn these points for the family. You only earn the highest bonus you qualify for, not adding all bonus points together (i.e. you get 1 point for $11,000, NOT ½ for $9,500 then another 1 point for $11,000).

College Bonus Points
A total of three points can be gained at college. These points can ONLY be earned by your heir or heiress. You can still send other siblings to college, but only one may earn you these points per generation.

One point for graduating Summa Cum Laude (4.0 GPA, no less)
One point for having 15 friends or more at graduation (they don’t need to be best friends)
One point for graduating with a net worth greater than $20,000 (If your heir (ess) lives with other Sims on campus, divide the house’s net worth by the number of Player Sims in the house. If it is greater than $20,000, you can claim the point)

There is one downside. If your heir (ess) drops out of college, or is expelled, you lose one point. You do not get this penalty if non-heirs leave college early.

College penalty.
There is no denying the fact that college graduates bring lots of money with them. Left unchecked this would inflate the family’s net worth score. To counter balance this, you will get a –1 penalty for every 5 Sims that move into the legacy house from college (rounded down). This could be heirs, spouses or just friends from college.

• Blood-line: Is the path between the original sim and the current sim. Cassandra Goth is a direct descendant of Vincent Goth, Because her father is his grandson. If Dina marries Mort, any sim child that Dina had by Michael Bachelor (here labelled Sim1) would NOT be a direct  descendant because their great-grandfather is not Victor.
• In-breeding: If Sim1 were to marry Cassandra Goth or Alexander Goth - then this would be inbreeding because they share a grandfather. Special case scenario - is alien technician 7 - Although this is the same sim, it is considered a different sim each time, for the purposes of the game.

What happens if I have a child that's a direct descendant not on the lot, and all my direct descendants on the lot are dead or gone? The challenge ends unless you can move the sim back by marriage to an on-lot sim (and get the penalty for in-breeding). Sims can't move back into the legacy house without that.

Can I suggest an extra challenge? Yeah - in the first few generations that's ok to do a scoring one - so no-one is penalised for starting earlier, otherwise yeah - but only if they're no-point scoring challenges.

So for example if you think up a challenge that can be completed in a generation - then that's cool. If you think up a challenge that needs all 10 generations - then it won't add extra points to the score, but we'll do something for it - I just don't know what yet, and only if all participants agree.

What is a platinum tombstone? If your Sim dies while in a platinum mood, it produces a platinum tombstone.

How do I find my Sim's lifetime want? If you have the University expansion pack, then hovering over the aspiration bar, will bring up the lifetime want. If you don't have University, then you don't have it.
