You can only have one space yard per planet in SE4, and each SY can only build 1 ship per turn. There is no way around it. A comprimise had to be made.

In Risk, you get 1 army per turn per 3 countries, not per country. You also get bonus armies based on control of entire continents. North America gives you 5 extra armies per turn, for example. Neither of these are really representable in SE4 if each system is treated as a country. Geo's system of one planet per system and one SY per planet, building 1 ship per turn at every planet, is good enough and maintains the basic spirit of the game.
