Well, that's disappointing. Me thinks it would have been better to have different regional markets. At least that way the game could better model the competition btw the great powers to gain access and even complete control over any given market, as well as how undeveloped nations were pretty much dependent on the great powers. How will blockade work with world market?
For example, during this period Latin America was totally dependent on Great Britain to sell its raw goods, and buy manufactured goods. It was also heavily dependent on said nation's banks and investors to "modernize" after the 1850's when liberal regimes took over most of the area. By 1890's most of the area had become "colonies" to GB, as GB had a lot of influence on the internal politics and economies of the region.
I would really love to see something like this:
World is divided into different regional markets.
Each regional market is represented on the map as a COT( kind of like EUII)
Nations gain "shares" of the market by sending "trade embassadors" to improve their standing on the region.
This in turn makes nations in region more favorable towards whomever gains the greater share of the market(say GB), allowing GB to gain favorable trade agreements that open up doors to encourage their rich, fat capitalist to invest there, increasing the influence in the area.
With increasing area of influence comes increasingly greater control of trade in the region. Pops in the region buy most of their gods from GB. If nation wants to borrow, they borrow from GB.
High militancy/revolt risk causes foreign capis to invest less or not at all
There is a revolution, regional nation can try to nationalize foreign investments, not pay loan--> Gb can use GunBoat diplomacy, blockade nation's ports and access to the market, forcing it to do what GB wants it to do. Which of course, can have diplomatic consequences; other nations in region become less favorable to GB/badboy?
