Went out and bought this today.
I wish they had made the box a bit bigger, as especially the red dragon is going to need some hot water repositioning of the wings, and I don't think the card components have the same high quality finish that ST:AW and SW:XW sports.
That being said, a lot of components are BIGGER in this game than we have come to expect from playing its two predecessors. All the fiddly markers have been upscaled to a size where they handle much easier and is not so easily dropped by butter-fingered players. This is nice, and I hope FFG does the same for Star Wars: Armada, due out first quarter 2015, if I remember correctly.
A quick read-trough of the rules booklet reveals that the basic system save a few twists, is the same as in the two sci-fi games. There are some interesting features regarding upgrades, and armour, and generally speaking it seems that WizKids have tried to capture the D&D 'feel' with their tweaking.
One fun feature is the TWO manoeuver dials for each dragon type - one for flight, and one for trampling about on the ground.
I hope to try the quick-play rules with my daughters tomorrow, and then a basic game with some upgtades and expanded rules one of the next days.
