Movement cost?

[kristoff]

I want to ask about "movement_cost" effect. Roads (as buildings type) have it, so it seems it should work locally (on province basis), but there is also one idea event and an effect triggered by it (IIRC, "imported ideas"), which reduces "movement_cost". The latter one is a country modifier so it seems this effect should work also globally. So I applied it to one of National Ideas, chosed it in-game, but I cannot see any increase in speed units travel through map with. Does "movement_cost" work at all? Is it only provincial or also global?

I did an experiment some time back (meaning before 2.2) and it worked globally. The easiest way to see this is by setting the global modifier above 50% because then units are unable to move out of provinces with roads (combined modifier turns movement negative).
