Aza Raskin's modest proposal :
You start with no pieces and as the game opens, you build lots of weak little ships. Their physical size means they don’t take much material and print quickly. That fire power buys you enough time to invest in building stronger big ships. These might take upwards of 15 minutes to build, but choose carefully, you’ll be blocking your production queue. With your 3D printer behind a sheet of cardboard, your opponent knows that you are are building, and for how long you’ve been building, but not what you are building. The whirr of your stepper motors give tantalizing hints of your strategy. Of course, you’ll be able to cancel production mid-way for an incomplete downgraded/vulnerable piece, like the partially constructed Death Star.
