Its been a while

IGC-scenario
Several months passed since I started this thread, so now here is the
expirience I aquirred in months of Portugal play.
Trade posts are useful if you dont have enough money to build colonies
and you dont want to lose settlers (max 6 in "stock").
Besides this(I hate when settlers go in vain

), level 6 trade posts
generate production income in rich provincies ,that canot be colonized without a counquistador.
And last but most important, Portugal always recieves a cot in india,which takes over most of Delhi`s trade + rich south China provincies....
This is especially useful(profitable) when Spain doesnt have a cot in
indonesia(usually opens in the Fillipines

).
What I think is not right is the fact that placing a colonist in north american provincies and some brazilian results in a self-buildin city over time, while in India this is not possible.
If you place a setller in delawere for instance, over time it will grow into a city, while african,indian, and indonesian provincies all have - % growth rate...
A trade post owners nightmare: An army of 1000 men lands in your trade post and continues its way burning 10 of your expensive-setller- costing trade posts and than populating it with its own colonists.
