The symbols you see are the main game
Assets of your nation. You need them for most actions. Some are not necessarily produced by factories, while others obviously are.
We have:
*
Gold: state funds. The money used by your nation for its military budget mostly
*
$$: private funds. The money used in the economy (
e.g. you can use it to build factories and railraods, not state funds here)
*
Coal
*
Steel
*
Goods
*
Recruits (with a subdivision between officers and conscripts)
For instance, a warship will need almost all assets except private funds...while a car factory will need private funding, coal, steel and goods (but no state funds or recruits)
