A couple of questions, most likely for MichaelM but we'll see.
Are the required levels to get an improved CRT hardcoded? They are as comments in land.txt but it does not look like they can be modified.
What does "blockade = yes" mean in naval.txt? Interface.csv says that level 0 allows warships, galleys and naval transportation. Is that it?
Is it possible to move effects to other files? For instance, would it be possible to have level 3 Trade allow refineries? If yes, is it possible to have different levels required, say Infra 2 and Trade 3 for refineries?
