@raenic and frozenorangejuic your families sound crazy! I never increased the population cap for my families because I was worried it would make my game lag. Also, I can only deal with that many kids before they start boring me ;) usually after the first 3 I do not bother and send them to boarding school anyway.
the risky settings, i guess you could calculate how many kids will happen the way you play the game frozenorangejuic: if you have 7 woohoos per week and the chance of conception is 20%... i don't know this type of maths always does my head in. give me some algebra any time but stochastics bend my brain lol. i tried to figure it out but this is as far as i got. 20 percent means a probability of one in five. that is more likely than rolling a particular number on a die. so quite a high risk, i gather. i guess if you set it to 10 you might be better off? sorry, massive fail haha :D
you could of course just google your different mods and see which ones offer the option of removing the cap and how to change the settings. how many can you have at once in your game?
