I posted a similar challenge on the Sims2 site when it was active. not sure of the right category.

The goal of this challenge is to create (through gameplay) a group of sims that could be considered part of 2 or more generations with as few of sims as possible.

start with just 1 adult couple or 1 adult sim; created in Create-A-Sim/Create-A-Family in a newly created neighborhood.
then produce offspring through pregnancy and/or adoption.
and those offspring produce offspring.
and so forth.
eventually 2 different generations will need to marry & produce offspring.
all playable characters in the neighborhood being descendants of the original couple/sim.

can not have/do any of these (through any means)::
-incest
-self pregnancies
mods/hacks/cheats/programs can be used for other things than those.

abduction caused pregnancies; if 2 or more abducted sims get the same alien for the pregnancy, that would be counted same as incest.


scoring (optional)::
+5 for first sim that is part of x generations; +3 for each after that one. x being 2 or more.
+1 for each engagement, +2 when one of them is a multi-generational sim, +3 when both of them are multi-generational sims; times 2 when they wed, times 3 if they have a honeymoon, and times 4 if the honeymoon is from a wedding party.
+1 for each pregnancy, +2 when the 2 parents are wed to each other; times 3 when it produces a multi-generational sim.
+1 for each adoption, +2 when the sim is wed; times 3 when it produces a multi-generational sim.
-1 for each death; -2 when it is a multi-generational sim.
-1 for each sim taken by Social Worker; -2 when it is a multi-generational sim.
-100 each time incest and/or self pregnancies occur.

have not yet encountered others. Can you provide links to any of those challenges?

To everyone:: changed one thing about the challenge.

Searched this site for both members. The search for SeriSims revealed no results. The search for Dicreasy had results, but did not find any details about the Victorian Legacy.

One difference between legacies and this challenge is that legacies seem to be about producing many sims. Part of the goal of this challenge is that there be as few sims as possible.

It seems you interpreted multi-generational as many generations.
That is not necessarily what this challenge is.

the intended result of this challenge is sims that are part of 2 or more generations.

changed the title.

added a point system.

already had restrictions.
from the opening post::

making this post to notify that I edited some things of the challenge; also the point system.
