Has anyone tried to use the extreme version of the road pillaging to essentially bankrupt all the AI, force them to disband all but a few units, and used it to walk through the AI's territory defeating the few units that remain? Or does it force them into high free-unit-support governments?
I don't believe that such is legal for the HoF. I mean, if you're injecting massive amounts of gpt to the AI, like LordOfDread was in his save, which you then don't maintain paying for since you injected it when buying luxuries, it sounds to me like you would end up taking more than they can afford, as I said in
this part of that thread. You can take whatever gold and gpt that an AI has on the turn when you make the deal though.
That said, taking every gpt that they do have when they have it available does work out as sufficient to have large amounts of gold and upgrade/purchase a large army. They change governments like normal with such. For an example on how to keep it all legal, here's one part of my Huge histographic games thread
in particular. Actually, if I were to do that again today, in order, I would have taken 40 gpt from Babylon, bought the gold back. Then pillaged. Then I would have gotten the last 6 gpt from Babylon for 108 gold. Then bought the 108 gold back with the final luxury deal before the turn ended. I would pay extra for buying the gold back, but it would only last for one turn. So, it would still end up profitable enough.
I think it pretty simple to keep things clean, I think. Just pillage first.
Also, I've found that sometimes it's not exactly optimal to pillage every single turn. If one purchases iron, for example, one can get it via a technology. Then I think one doesn't want to pillage until there's another technology to sell them or enough new gpt to pay for that iron.
I also provided another
example in this thread.
Perhaps also of interest:
By a horse-knight build, or horse-calvary build... I let the horse build finish, then I zoom to the city, and upgrade to a knight or calvary. I do this by first disconnecting any iron or saltpeter sources, either by pillaging the source in my territory with enough workers standing on the tile ready to reconnect (so industrious workers work best), or if I acquire iron or saltpeter from the AIs (both of which cost a significant amount, though they do come as worth it) I cut the trade route with the AIs, then make sure I have horses connected... I might also purchase horses for gpt, at least initially... I know I did in this Mayan game. Then I change all my relevant builds to horseman (if a city builds a bank or marketplace, I won't change that, of course).
I also make sure to acquire any techs, if not doing any research, before doing the next step (if I will learn a tech the next turn via research of my own, it would change the horse build to a knight/calvary build). Then I reconnect the iron or saltpeter, or both one way or another. Then on the inter-turn, I zoom to the city and upgrade the horse to a knight, knight-type unit, calvary, or calvary-type unit (though I haven't played with Russia or the Ottomans doing this, it should work in principle). The knight/calvary then sits ready to go on the next turn... without having lost any time in the upgrade process. Of course, horse-knights and horse-calvary won't work for India, and I doubt for Japan (though I haven't tested them).
I would buy some granaries and other infrastructure like courthouses. Then later maybe have a 10 shield city start on a horsemen, shortrush an explorer, then finish the horseman, zoom to the city and upgrade to a horsemen. Or go worker -> explorer in a single turn then finish a horseman -> (zoom to city) cavalry. Or spear -> muskets. Or find a city with 20 shields later and go worker -> temple (or granary if sold at size 12) and then finish the rifelmen. Also, some upgrading of trebuchets to cannons. And later artillery, in games where the AIs have learned Replacable Parts like the 100k game with Babylon.
So, the first "big use" of AIs gold goes to upgrading.
The second "big use" of that gold I did consisted of buying armies in a corrupt city with The Military Academy.
For how much gold I managed to pull... here's
one fairly early image from the France 20k pangea game. Also, near that image, I manage to
disrupt a trade route with a military alliance and get more gold that way. +1135 gpt a few turns
later. 10744 gold and +1131 gpt in
70 AD. The peak amount of gold I kept in my treasury
might have happened at 190 AD for that game. More gpt in
280 AD, but less in the bank. Oh... I was doing heavy research also in that game! The histographic games used more of the luxury slider in the middle ages and didn't maximize gold also, though I think Drazek didn't use the luxury slider as much as I did until the post war age. There were times I temporarily set the tax slider to 0% to make a deal or something in the France (and other) games. I took a picture from one of those times it seems.
We see +2930 gpt with 6361 in the bank. That's enough gold per turn to purchase a worker->army and make a few horsemen -> cavalry units every single turn! Usually, I haven't done both. But, there have been a few times where I've felt I've had enough gold to both purchase armies and upgrade units for a turn or three.
Happy upgrading!
