Extensive large trading port

[Teleklos Archelaou]

We limit which places can get big trade ports, but even if a place had a poor or small port for large scale trade, we thought if we could allow those places with less than terrifice natural ports to be able to have big ports - but it would take some incredible efforts to reshape the ports to get them better. So the bonuses just equate to one step up in level, but the cost and time should be prohibitive generally, unless you have built everything else pretty much.

We don't expect people to build them except in special situations - and anyone who does had better be really rich and really bored!

Exactly... Bored and rich... That's when i always built them... When i was bored, rich and had nothing else to build.

Well, not like Taras is gonna be doing much of anything anyways. Too far away from any battle to be worth recruiting from, and I have a glut of cash from all the exterminations of the white plague.

[Kralizec]

Well, the AI will build them regardless of the huge cost and build time, so when you move in and evict the incumbent you'll already have the large port without having done anything for it...
