Thanks for your input guys.
The miniatures would be
BFG size / Firestorm Aramada. So big enough to see the difference. I just ordered some 2mm and 3mm magnets to see how they behave and if we could make Turrets with Magnetic bases.
The Orders would usually allow some minimum movement and turning (1/2 of maximum) and firing 1 location for a squadron. Then by passing a Tactics roll you would gain additional benefits such as a Full Move, or Turn, Firing all weapons, Re-rolling hit dice etc.
After playing Memoire 44 it was frustrating when sometimes you didnt get the correct order to move on one side of the table so we are avoiding Orders that limit your options too much.
I have just been cutting out all the play test cards, you can see the three custom dice types we be using. As well as various cards, for orders, weapons , shields, engine, and bays.
