Most despicable thing you have ever done to your or another civ

[DroopyTofu]

It's also pretty bad if you have the country to your north and south start a war when you have OB with both, then you cancel OB with only one, making it impossible for them to invade the enemy. For example, if Canada and Mexico got into a war and America refused to let Mexico send its army through the US to get to Canada, but Canada was free to send units through to attack Mexico.

I have seen the AI do that to each other, which is hilarious.

As the founder of Judaism with the Apostalic Palace (playing as Boudicca, see the '1st Impressions' link in my sig...) I accepted the gift of a city from the Greek Rebels, thus causing the 'true' owner of the city (Cyrus, also Jewish) to declare war. I took one of his cities, saw a SoD heading my way, and forced through a resolution to end the war. I swear his leaderhead looked disappointed the next time I saw it...

If you REALLY want to continue pising him off, ask for his cities every time the option comes up

Will do!

The worst i did was, i think... When i backstabbed my ally Zara, just for the fun.
I had 2 vassals, and knew i was gonna win anyway, so i made Shaka (who had 12 cities, huge sack and a vassal) attack Zara, just because i didnt want to backstab him myself but wanted him to die anyway.
I refused both Zara and Shaka's help demands, but then... I saw a Great Merchant, belonging to Zara, going to the land of one of my vassal. I just coulnt resist, i declared war on Zara and murdered his Great Merchant.
Then Zara was at war with Shaka and his vassal + me and my own vassals, in other words he was against the whole world, just cause i've been too lazy to attack him myself.
Even after taking out his GM i didnt attack Zara; but anyway my 3 vassals were between Zara and me, so i let them do the job xD

for over 4000yrs, regiments of loyal axemen have served me well. But when I realized I didnt need any extra miltary garrisons, rather than choosing to modernize the loyal unit, I send them off to suicide missions so my new toys don't get a scratch. hows that for a betrayal.

 

[Sir Sam Vimes]

that's just evil...

 

[Archon_Wing]

Chariot rushing Liz down to one hilled city where I couldn't take. Damaged chariots attacking a hill =no Called a cease fire, and two turns later I see archers leaving that city, leaving one defending archer and a few somewhat healed chariots of mine near her city...

"Oh cease fire? I was just kidding!"

Elizabeth's body was promised a burial suiting of a defeated monarch, and thus was casually dumped into the nearby river.

Asoka didn't like that and I got another -1 though.

If I'm feeling particularly despicable, I automate my workers. Clearly that's a fate worse than death.

I used to do that in one of the earlier Civilizations.

 

[i_imperator]

I have nuked and burned an entire civilization to the ground in an instant.

Heh Heh, I have done the same. I have also managed to destroy civ's that were about half an era or an era ahead of me just by using nukes, mariens,fighters, and paratroopers.

I have won games, but Rexing, and then proceeding to rush buy tons of ICMB's so i can vassle the radioactive civs who are forced to vote for me in the UN. Now thats democracy and diplomacy at its best

 

[Dida]

The Incas built countless wonders and beat me by a 1-2 turns several times to some very important wonders. I was so jealous and furious that I went to war and razed all of their cities. I was going for a space victory.

 

[Bad Brett]

Sometimes when my neighbour declares war, I'll realise that my defending stack doesn't stand a chance against his attacking stack. So instead of letting him slaughter it, I'll leave my poor citizens completely unprotected and move the stack to one of his cities instead. He'll capture my city, but in the meantime, I'll raze one of his cities! He'll become angry and move his stack to the next target and this is when I take back my old city. Hopefully, he'll be confused and his stack will spread out now.

Perhaps is not really that despicable, but I really enjoy razing cities I know I won't be able to keep.

The AI can be much worse, though. It can drop 10 nuclear bombs on your SoD in it's own territory, obliviating both your army and its own citizens.

 

[ajsciri4]

Oh, I've organized nearly the entire world against the strongest civ before

 

[Akbarthegreat]

Not really despicable:
I was playing Rome E-18 civs, had conquered Europe and Arabia, next was Egypt. Took Thebes, so culture from Athens spilled over onto the wheat tile. The wheat farm was unpillaged, so Hatty sent an archer to pillage it. And guess what, it triggered a Golden Age['A roman defender has run hundreds of miles to warn of invasion' random event]!!!! Imagine me, who was conquering the whole world, and sending tons of praets in SoDs to kill others, and those poor guys just sent one archer!!!! Imagine yourself in Egypt's place. What would you do???

 

[slengtorm]

Not sure it's quite in line with the spirit of the question, but I'm currently playing the Mongols and I generally enjoy changing the names of conquered cities to match my civilization. I renamed a former Spanish city "Moron" (yes, like the city in Mongolia) just so I could see the announcement "Moron celebrates 'We Love the Dictator Day!!!'"

I have another story of Slavery that happened yesterday:

In my last game, I reached Oxford at about 1 AD, problem was, I was almost through with research to that point as my Vassals would continue from that point on and I had enough tech to get everything they'd research till the end of the round, so:

This time, I decided that I wouldd rush those stupid Universities. I had 15k of in the Bank, so I first decided that I would simply buy them. Then I saw, that 1 is freaking 3 so 8 Universities (and some cities even needed the Library before that as it was 600 BC or so and I barely had Granaries, Forges and Courthouses) would eat up my whole money, leaving no place for deficit Research as I was running -300 / turn at 100%, so I decided:

Whip them!

As I played Incans (so no SPI) I could not switch to OR (was running free Religion) , so that made 8 5pop-whips which was half of my Population or 6M happy Incans!!!

They didn't cry that much, just some people bragging about that for about 300y, and when the new University of Oxford was setup in Cuzco, Research was even higher then before the loss of half the Population

Guess I must have slain some really dumb people and by that produced some really intelligent ones

 

[JBryan314]

I was playing as Roosevelt (I usually do) and Churchill was friendly towards me almost the whole game. Tradin techs, resources, defensive pacts, open borders, we were neighbors, the whole 9. I built the U.N and he won the initial election. So I broke all ties, declared war and wiped him off the map. I still feel sorry about that. Haha!

 

[JBryan314]

Also, in the last game, Saladin built the Apostolic Palace. So I marched my army straight through his territory and razed Mecca to destroy it. Then I left. That was all. End of the war.
