Pools I could live without...for awhile anyway. Toddlers, that's another story all together. Life simulator, birth to death, yeah, toddlers are a must. It's not that hard to put together a toddler mesh and it's not that hard to animate it. If they really want to be that lazy, why not rip the meshes and animations from TS2. After all, TS4 is looking like a true sequel to that game. To be honest, I was hoping to see simulated growth in this game. I guess they took the cheaper way out.
I also have a big problem with teens being the same height as adults. Hopefully some wonderful modder will get hold of the source codes and remesh the teens since EA is obviously too lazy to do it right the first time around.
The CAS demo is interesting, but it's lacking in detail ability. The "stretch/pull" limits are too limited. So far I've been unable to stretch any area of the face far enough to create some of the more distinguished celebrities. I'm sure someone will rework the hidden sliders a little better soon enough though.
Not too thrilled with create-a-style being omitted, but the color picker isn't so bad. It could prove useful if it can support more than just a few recolors. I am somewhat looking forward to seeing the kinds of CC (clothing/objects) the new game might be able to support. Maybe a better default skintone would help the overall look of the sims themselves.
