I was next to Peter, and he was Buddhist like me...he demanded Liberalism from me, I complied, and he promptly went FR.
Obviously, this was a big downer...because the most militant of the players in the game was on my borders, and I had 4 of his cities under heavy cultural pressure.
So when Washington declared war on him, I refused to go to war with him when Washington asked(duh!). However, when Peter asked...I was at +4 with him and with Washington. However, I mistook Washington for Roosevelt on the map, and figured he wouldn't be able to reach me unless he completely took out Peter on the way...which, if it happened, would be a big downer for me game anyway. So I agreed. Peter was happy with me again, even though I took Smolensk from him the next turn via flipping.
At this point, I've gotten the only two religions that have spread to me placed in all my cities, and I've got all the temples built, Hermitage built, and I've got 1 cathedral building left in each of my legendary cities, then I can go full culture. I've also already got 3 GAs saved up, while I have a single GP farm and 2-3 artists in every single city for a bunch of mini GP farms. At this point, I haven't even used my slider yet and Paris and Orleans have both passed 8k culture, while Rheims is nearing 6k. I figure I'm in good shape, the AI are teching fairly slowly, as I'm about to go all culture and still have 3 techs up on one of the AI.
Unfortunately...my last randomly exploring warrior bites the dust...in Elizabeth land...on the OPPOSITE border from where I thought Washington was. It turns out, I thought Washington was where Roosevelt was. Washington is 1 AI away from me on the opposite side of Peter, and that AI, being Elizabeth, and being the worst enemy of 4 different AI, is one I have no relations with. Unfortunately, bad news happens in 3s. I find out that not only did I confused Washington and Roosevelt, but he has a stack of 7 Cavalry, 4 Trebs, 5 Grens, and 2 Rifles coming toward Rheims. I quickly cash rush a couple cats, pull my defenses out of Paris, Marseilles, Orleans, Avignon, and Lyon. I upgrade as many of my warriors to Grens as I can, and I switch to nationalism to draft some muskets. After two turns of drafting, I find myself with a decent defense in Rheims, but a defense only...there's no way I'll be able to kill any of his units on the offensive...I'll have to wait until he attacks to get rid of them....then the worst happens...Orleans falls victim to a sneak attack by a single American cavalry that was hiding in Korean territory. Orleans had no defenses because I'd pulled them out to deal with the obvious threat...I had no idea that the AI would go around my territory, sneak through someone else's territory, and attack on a different front!
So I lose Orleans...I lose my 3 saved GAs, because I'd sent them there to get away from the frontlines....and the next turn, I lose Rheims when Washington suicides all his trebs then takes out every single defender I have at the loss of a single Cavalry...against my pikeman, that I had upgraded a warrior to ACCIDENTLY. Oh...he razed them both too. After that, Washington was willing to talk peace with me...for my entire treasury and 95 gpt. I agreed and quit the game.
