Thanks for the prompt reply, guys!
In my second play-through, on the Marathon setting and with a Gigantic world, I am the Russian player with a total of five colonies (including a fresh 1 pop settlement). My colonies are individually quite large but I have struggled to match my colonists skills with overall production focus.
I did not think to take advantage of interactions with the native tribes when I arrived, and aside from a short, sharp, and unsuccessful war with the Comanche, I have had minimal exchange. One of my native slaves did eventually escape. Im not sure how to prevent such problems, as garrisoning does not seem to help. With respect to the Indians, I plan to build a fort in one strategic location and then, at some future time, conduct a very limited war-for-profit against the Comanche, who are the most warlike of my neighbors. Unfortunately, opportunistic raids by various other local tribes have not resulted in captured labor.
I prefer slaves to indentured servants or pretty criminals, and free colonists to slaves for most tasks. I find that there is too much cost involved with keeping slaves. The chase means lengthy production stoppages, and sending a garrison to gallivant around the countryside, even when one is at peace, risks unrest in my cities (soldiers being expensive, and therefore rare). Does anybody have any thoughts on the use of slaves? Highly productive laborers at >400 per unit are hard to beat early in the game. Heck, Im have so many problems populating new colonies and balancing various demands that it may be time to turn back to slavery in a big way.
The suggestion to kill sea animals is a good one. I did not think to use my sloop in that manner before it was destroyed by a pirate frigate. I think I may buy another sloop soon and try to beef it up.
Thanks to the only beneficial decision my monarch ever made on my behalf despite constant bribes, I received a large shipment of Hessians and artillery, along with a ship-of-the-line, on the occasion of his declaring war on the Dutch. I was able to use a portion of these troops to successfully capture the Dutch capital while also seeding detachments as garrison troops elsewhere in my empire. The ship-of-the-line has been highly effective in sinking pirate ships, though I dont feel as if Ive actually suppressed the practice. Fishing vessels, once a prime source of food for my empire, are all but useless. I have one such vessel, shepherded by the man-o-war.
As for pearl diving, thats exactly what I was wondering.
Im designing a 4X forum game of my own, and youre all more than welcome to sign on as players or designers. Its based on Sid Meiers Alpha Centauri. In short, I dont have it in my to mod this mod, although Im chock full of good ideas and potentially useful knowledge regarding the history of colonial North America.
