For me I would a Twilight Imperium :Armada. ( I'm sure someone has posted this one already but I just had to say something myself.)
I would be ALL IN on this FFG property as it gives them freedom to make any style of ship and with 10+ races you have a great amount of options and new abilities for each race type. It endless on what they can come out with. Not limited to just 2 factions and scum, maybe. Don't get me wrong I play X-wing and that's great. But the full potential for the Armada system, for me, could be seen in the Twilight universe.
(If they wanted they could make it compatible with Star War as well.)
If you had to choose which race would you see yourself playing as. SOL, L1z1X or maybe Hacan.....ect... So many options.
Who know if we all just 1+ this maybe they will take notice. Here's hoping.
