If we do have a Sims 5, should they add a height adjuster in the base game (or in a pack)?

Solution to the problem. Unity 5 engine has character scaling...supposedly where you can tailor the bone-structure of the sims to the animation allowing the animation to be used on characters of different heights.

Sims 5 needs to push the envelope...and not stick to the "lowest common denominator" for programming. It's time to see just how good Sims 5 can get in terms of gameplay as well as graphics.
