The world market is the market without borders and will always be active. It's been around since the very first 2010 game. This is why its important to keep that rating positive.

we call it black market, existing since human invented trade. So it is historically quite accurate.

Also, on the day trades. There's a hidden nation within the game that stimulates a market. They produce goods, buy and sell. It also helps with major resource shortages later in game.

Yeah, Defcon was kinda fucked in the later series. Up until 1936, you was able to change your DEFCON. Don't understand why they thought it was a good idea for AI to be in control of such thing, but ya know. Also dread to think what your casualties are.

no idea dude still was selling shit fine by me, but my defcon was at war for somereason... wasting all my money i was spending like 300 billion on it

your budget is positive thanks to foreign trade but there is only a single country, you trade with?
