Fast game play with more models that act like X-Wing ships. On the spot planning and moving but more skill involved when moving and doing things becuase you don't always just "Move, do X and shoot".
As an Armada player this hits home becuase of the planning but as an X-Wing player you have the advantage of knowing the movement and the predictions.
Painting is also something fun for you all to do and they are pretty easy to paint.
