Markets have no effect on the commerce going to lux via the lux slider in the F1 screen. The editor allows you to add this effect to a structure, but there is nothing in the normal epic game that increases lux-commerce.
Markets only effect the happiness from lux resources.
Not to jack, but I've been wondering about the net effects of lux and marketplaces without other happiness boosting factors such as mp and temples etc. Say on Emp and above, with a market and 8lux, how much effect would it actually have?
lux resources and lux commerce create
happiness.
Buildings, wonders,
military police in some governments, and difficulty bonus give contentness.
If I understand it correctly then:
A happiness effect will always first turn one content face happy. If a city doesn't have any more content faces, it will turn an unhappy face content.
A contentness effect will always turn one unhappy face content. It will never create a happy face.
At the highest difficulty levels:
the first happiness will turn the free content face happy.
the second will turn the 2th citizen content
the 3th will turn the 2th citizen happy
the 4th will turn the 3th citizen content
the 5th will turn the 3th citizen happy
the 6th will turn the 4th citizen content
the 8th will turn the 4th citizen happy
At regent/monarch diff:
the first happiness will turn the 1th free content face happy.
the second will turn the 2th free content face happy.
the 3th will turn the 3th citizen content
the 4th will turn the 3th citizen happy
the 5th will turn the 4th citizen content
the 6th will turn the 4th citizen happy
the 8th will turn the 5th citizen content
At warlord diff:
the first happiness will turn the 1th free content face happy.
the second will turn the 2th free content face happy.
the 3th will turn the 3th free content face happy.
the 4th will turn the 4th citizen content
the 5th will turn the 4th citizen happy
the 6th will turn the 5th citizen content
the 8th will turn the 5th citizen happy
