I've been giving this a go, and have finally thought up some rule sets. It kinda draws on the Doublacy Challenge (please don't sue me!)
Idea of Challenge - Each birth is a twin birth. You can only do this challenge if you a) own OFB or b) have a twin hack installed.
New Rules -
1) Every birth must be a twin birth (see above)
2) You may not bring back any pregnant sims from death
3) You may not have any mood modifiers (including the energizer) - That's the whole point of this legacy! See how many times your sim-parents come near to death!! Oh, and the whole enjoyment thing too.
Scoring
+2 - 10 Kid Want (Although it is twice as easy in this challenge, it is twice as hard raising every child!)
+1 - every twin birth
+1 - every sibling goes and completes college (per generation)
+1 - All children get into private school (per generation)
+1/4 - Each sim that makes it into elderhood
-1 - Each time the Energizer is used
-3 - Every birth that is not twins
All other original scoring applies.
Other thoughts:
You could do a Black Sheep Twinacy, where you kill off one of the twins and keep the other as a heir, or if you have more than one set, kill ALL THE SPARES!!!
Please tell me what you think....
