So FFG really made awesome games with X-Wing and Armada and rightfully jumped to No.2 of most selling (tabletop) games 2015 with that from nowhere.
The (new) ideas of FFG are great and refreshing. However GW seems to have learnt some lessons too. With their rebranding of Fantasy to Age of Sigmar they did a plenty of awesome changes. I have the impression many of them were inspired by FFG (I would have whished they also would do special dice too).
However they also did some good things on their own. I really like that there are no points in Age of Sigmar and no forced "even" battles. My main concern with Armada is, that in real battles you will do anything to ensure there is not an even battle. I really love how Age of Sigmar features uneven battles, balancing everything out with the mission and victory rules.
