What’s the cost for expanding existing tech? To use the example from the book, let’s say someone gave color for a fleet, and made a Resources roll for the sensors. Later they need weapons to fire on something. Do they need another color scene, or do they just test Resources?
In other words, is the cost having to make another roll in a system where the total number of rolls is strictly limited?
Also, is it possible to build on another player’s tech- if in the prior example the player’s lieutenant (also a PC) was the one who needed the guns, could he test for the guns and use them (assuming he had the fleet-owning PC’s permission, of course)?
