LOL.. yeah .. it's true and the reson I didn't properly quote you was that I was in such a hurry yesterday and I forgot where I found it. Usually I browse all threads and copy any guides that I need into my own 'how to' for easier reference.

After hours of searching (exegerated) here's the link:

It's under the title Comple EDB guide if I'm not mistaken on page 7(?)

About my question, yes currently I can have both type of ports though I restricted the naval port to timber provinces only , but all province can build trade port. I'm currently trying to do ala Roma mod base on RTR 6.0 gold and one thing I dont like about is ports are giving too much income. As Roman once you control all of Italy and Sicily and without recruiting more 'legions' the surplus can get to more than 100K. Too much.

That why I'm giving options and choices, like if you want to balance to be easier (in theory) like trade port brings trade income and war port bring navy vessels but creating a negative impact on trade. The catch is you can only choose only one.

Will work it out on my long week chinese new year holiday next week.

Cheers.. thx.
