templar_x you can't just leave us hanging on how you achieved such a "non optimum" victory of 550ad on Diety. I reread your first spoiler and it sounds like your game had stabilized after a brush with Egypt. Can you elaborate on events that lead to your win?
Sometimes bad luck can be overcome by much better game play which you have shown to have. Any tips?
i will try to give some Information. unfortunately i did not take any notes in that game also, as a part of the Efficiency program that allowed me to finish that game before my holidays at all.
after the expansion phase, a good Portion of my eastern productive lands were in Egyptian Hands. however, they were the strongest civ at that time in nearly any aspect. and i was still despotic, so i for sure did not want to use legionaries against them yet and Trigger my GA. so i gathered, like, 15 horses, and attacked. this brought me some good space. still i had to pray not to lose it all again with my Slim Forces when Egypt fought back with immense force. i could get peace i believe on even Terms. so far for the first Roman-Egyptian war. if i remember correctly, that one already go me an MGL. i believe that first one was used to rush the FP in the new-found FP town in the eastern core, which seemed to be a nice spot.
my exploring galleys and curraghs had in the meanwhile contacted everyone. on the other continent Rep was discovered, making it a bit cheaper for me. if i remember correctly, i already Triggered the next war and my GA during the anarchy phase, but i am not sure about it. anyway it was a very practical Situation with loads of Egyptian Units in my land, and I asked leave or declare. (they were at war with Babylon, which had founded a town on the tip in the south)
this time i could decimate their Forces considerably. still it was quite the fight. like, two nations in war during their Golden Ages. i got like 2 more MGLs and iirc destroyed Egypt after two more wars. during the last days of this war the one against Babylon was prepared. unfortunately, Egypt built hardly any wonders, and no useful ones.
Research was practically stopped, i "traded" for techs from now on.
in the war against Babylon, mostly horses were used, again. they were relatively weak and fell easily.
not so Persia. maybe i should have let them alone altogether. i upgraded my force to Knights, but still their immense number of troups made Progress difficult. not the walkover that would have freed the troops up there soon.
a second fleet hat been prepared for the Moment when one of These Events should happen: "trade" for the caravel tech, or conquest of the Persian TGLighthouse. Astro came first. troops were assembled and i destroyed by then already weak Ottomen. English were much harder though. good i got MT rather soonish, i upgraded again and again made Progress.
most of the time i was at war with everyone. and kept them at war with each other at the same time. makes playing much easier, AW for everyone.

Money was used to shortrush and fully rush troops.
what went well was that i got the first 3 MGLs relatively early. Long pause after them, iirc.
what did not work out was the slingshot-gamble. and of course my lack of time.
