well, since i'm half-warmonger and half-peaceful builder, I wuz starting to get bored when I was way ahead of the tech reace...and i had so many obsolete swordsman and calvalry just sitting there

I saw that Persia was pulling ahead in tech suddenly, obtaining gunpowder. Since I had only 2 deposits, and was beginning to need LOTS of workers for my factory/pop pollutions, i decided to send about 30 units of calvalry, swordman, and cannons (except a detachment to defend home)...
LONG story short, with use of cannons and ironclads, i razed around 20 cities, kept choice 3 or so cities for myself, left around 3 or 4 cities to create buffer zone against other AIs wanting to expand into MY new territory, and got around 60 or so free workers from razing them ALL :flamedevi

...i just discovered replaceable parts, and with my own ~20 industrial workers, i'm having a blast...another thing is, i lost a source of coal, and a new source popped right up at New York, my 2nd best city, so now i can build Ironworks!!!!!
The only thing that's bugging me is only sources of oil that i have within my sight is far far away...=(...
p.s. I'm an american warlord, i have almost all the wonders so far with xcption of crappy great lighthouse, greatwall...3 or 4 turns/tech research, approx 500 golds/turn...around 1710 AD in the middle of industrial era...my enemies have yet to discover chemistry!! Soon, all the AI will feel my wrath...(turned off Diplo/domino victory)
