We put in 1000 to begin with just to get things going. But as the game evolved we've tightened up the numbers because part of the challenge of the game is managing resources. This is why we put in the new scripting "Repeat Until Storage" functions so a worker can check if it needs to make any more. In the final game there won't ever be a need to create 1000 of anything so hopefully it won't be too much of a problem :)
