I understand IC and Leadership grow as you build your empire. Is it possible to achieve 300 in production or 40 or 50 in leadership? Obviously this varies depending upon what faction you're playing and what part of the world you're growing into.
Another factor, effecting production, would be the availability of energy, metals, and rare materials. Spending 300 IC per day would require a 150 per day increase in rare materials just to maintain current levels. Still has anyone achieved these levels? How far advanced in the game do you have to be?
Just curious, and I know every game will be different.
