Jeese. I mean on Emperor and above every single comp player is just ready to go.
I was just playing an immortal game as Germany and of course waited to make my move with panzers. Its continents but I'm on a continent with 7 (originally 9) civs. 2 weak and the rest are comparable. So anyway, somehow Alexander was friendly with me and I convince him to attack the points leader at the time, Hannibal. He has a vassal. Then Qi Shi (2nd place, 1 vassal) attacks alex (i'm between the two position-wise and Alex has like four cities from a previous war right next to QI Shi from an old war). So I'm of course already outnumbered (I only had like 10 panzers at the start) but I have to go help Alex before I get double teamed so I declare war on China and then the Mongols, as usual, declare war on me. Followed by Survy (the last neutral on the continent) coming to my aide and the rest of the world (2 civs) declaring war on me and Alex. How ironic, I started a world war with Germany in the industrial era, but I did buck the trend and actually won.

It was the largest war I ever fought (1868-1921 on the slowest game speed).
421 military units killed, 50 lost, almost 150 manufactured and 24 cities were taken (a few mine but I got em back). And those were just the battles I was involved in directly. Alex and Survy did almost half the fighting on both fronts. So about 600-700 units and Alex took 5 cities and survy 1 so 30 cities. I had to go into total war mode: Police, Nationalism, theo, 0% tech. EPic.

Anyone else experience this? The entire world was like," ooo war... let's play."
The AI has been improved in the new patch. They all recognized that one side was busy and jumped in to take advantage.

actually, yes. i have seen this but only as the result of defensive pacts, i am jealous of you.

Normally in my games, when the AI goes to war with other AI they usually "pee in circles" exchanging control of 2 cites a few times. But this kind of massive chaos? I envy you. reminds me of civ 3, when you would see REAL AI wars where every 10 turns it seems like one of them dies

Sounds like World War I. Sounds like fun.

Sure beats the many times the computer can't even figure out how to get its troops to the war!

Way awesome. I've had that before, but probably to a lesser extent.

That's cool. I've found that the Next War scenario, for all its flaws, is good for that kind of all out war. Since there are only four civs, all it takes is one aggressive one to start a war and one opportunistic one to see an opening (both of which have been in ample supply each time I've played it). The fourth nation will either join in the fun or turtle and build up troops, guaranteeing a repeat not long after somebody's wiped off the map.

I had a game on Monarch where I had a WORLD WAR scenario break out due to defensive pacts formed by AP and vassals. There were eleven Civs, four were colonies. I didn't win, Roosevelt beat everyone into submission, but it was awesome to watch it all unfold, and try to fight him off. I was the only one he didn't conquer in the end, he won space race.
