There is no blue print how to play to this frustrating game. The last set I tried to stay with the cashier and bought the tech and the military, I can't buy spies so I make a lot of them. I lock on the bots banks money and take it for fast cash, before hitting them to have the money to build after I hit them no need to sell oil bushes, and besides I was losing 8 to 9 thousand bushels a turn, so I bought a million or so bushels, and kept a close eye on that account, I hate the shortages. It's costly , and oil I tried to stock it, but moving 3 to 4 million units, a hit, eats it fast.
