I'm all for broadside fleets! I was actually in the process of translating FASA's Leviathan to SAE when Nova was announced. Now I'm trying to evaluate whether to move to Nova or not. So far, Nova's the favorite for the reduction in die rolls among other things. The construction of weapons threw me a little though. I agree that weighting the effectiveness of arcs of fire should be an ORAT mod not an SU mod.
In conversations with Dan in the past it's been brought up as to the merit of weapons facing the direction of the drive being a little more expensive than weapons not facing the direction of the drive, with the logic that drive facing weapons would probably be easier to bring to bear.
I didn't know they were going to be weighted, but I think it's good that they are.
That being said, I agree that it probably should be an ORat mod versus an SU mod.
