I hoped for a spaceships/mechs/tanks book next.
Well, AA3 will be fun like the first two (a Nuar and Verthani are PCs in my group right now and a uplifted bear and an orc are the newest connections of them), but I have to say it: there are so many topics we can expand regarding spaceships and spacebattle.
E.g.: additionales shipframes
or several ships for the PCs (Fighters in a bay?)
Or what about a neural Interface for the Pilots with high IN and low DEX…
Switch bays for additional weapons, so perhaps a Option for three weapons in one area...
And regarding mechs - the Next step would be Transformers: mech now - spaceship later :)
