One thing that will have to be video-shown (i.e. a screenshot obviously can't show animation) is the new animation system in Beta 4.
In Beta 3, animation has worked like in all Stardock games in the past - unit is moving West. If they turn around, they instantly turn around. When they stop moving, they instantly enter the stop animation.
Animations were recorded at 24FPS also.
But in Beta 4, the animation speed has been increased to 30FPS (hardware is better now) and the new animation system supported blended transitions. That means when a unit turns around, it shows frames of them turning around. When a unit comes to a stop, it blends the animation between walking (or swinging an axe) to stopping rather than just popping into its idle animation.
The effect is very subtle but makes the overall game feel much more organic. IMO, it also makes it feel like an RTS with a turn button because the units feel like they're moving like they'd be moving in an RTS (which in this particular case is a good thing).
