There are no factories, at least not yet. What you can do is to sell your excess wood, stone, and ore for cash and then use the cash to buy leather, ceramic, and steel.
That does two things for you. Firstly, more valuable resources take up less room in the warehouse. I think the program treats 1 units of wood the same as it treats 1 unit of steel from a capacity standpoint, so a warehouse full of steel is worth far more than a warehouse filled with wood. When you are tight on space buying more expensive items is the way to go.
Secondly, the prices on leather, ceramic, and steel seem to me to be more volatile. If you need to gain money by playing the market, it is easier to make money by buying the price dips on higher priced commodities with volatile prices and selling when the market recovers. A 10% change in the price of wood may net $0.10 in profit per unit, while a 10% change in the price of steel can be $40 in profit per unit.
Great Game : )
You can beat all the epic levels without actually using an epic unit, here's how I did it:
Important spells are shield
Important units are phantom ghast and were tiger: why? because their attack animations boost them a fair distance forward,
So i use these units with a combination of other normal units depending on units of the enemy on each of the epic stages.
The phamtom and tigers will propel themselves past the major boss and focus on the enemy castle as long as you tell them to advance and the other units disrupt the boss.
Always have shield on, on epic levels where the boss does not advance by itself this is very easy, just wait for mana to build.
RECAST SHIELD when timer gets to 2 and you will reset to 20 with no time wasted.
Using this strategy i was able to beat all epic levels without using a titan unit, the last level requires a bit more timing but is definitely doable.
