Re: Height
It will not so much depend on bigger hard drives @Psychotps. It will probably ask a lot of computing power i.e. processor speed and Random Acces Memory. When you want to have the infinite numbers your calculated you will need something like a super or a quantum computer. But it is not purely the difference in height. When you look at the animation programs which you can use to make your own cc there is the possibility to install extra bones and rigs, thus you will be able to bend a neck a little bit extra. This results in not creating that much extra animation interactions. The Sims in CAS will look more lifelike as well, when there is the possibility of height sliders. I suggest that they could start with for instance 2 different body lengths for each cohort.
When they would also start sliding the legs or arms your initial calculations will be definitely more correct.
By the way, in a number of occasions i noticed that kids of let say 5-12 years seem to stretch more than would be "humanly' possible in their hugging interactions with older, grown-up sims. I never heard any one on any forum complain about these 'glitches'
