so my daughter and i had a family that we shared on my old computer. she made the dad, i made the mom, and we switch off every generation of the family and see how they go.
well i lost them when my computer died so we decided to make a new swap family! altho this time,m we build a house as well. in fact, we built the house first. (last time we just tossed them onto a lot and built from there)
i play this first generation, then when the kids are grown, it will switch to my daughter. she will pick whichever hier she likes best, and play the family untill THOSE kids are adult and switch.
we both have VERY different tastes when it comes to our sims, so it will be interesting to see how the genetics end up, considering who we pick and who we marry. should be a fun experiment.
the official rules are
the heir must be a child of the previous heir. it doesnt not have to be from the pairbonded couple (expect for me because im the starting generation) so if a child is born from an affair and its better than the others, its fair game
no editing genetics in CAS. we havent discussed if plastic surgery is ok tho.
and thats pretty much it. no rules. she can do whatever she likes with her generation and i can do whatever i like with mine. including altering the house or even moving to a new lot.
