i just finished emperor difficulty for the 1st time using mayans (indus/agri). it was an uphill battle the majority of the time. played on pangea 70 %. here's my victory status screen. https://i.imgur.com/lLAEkAs.jpg lots of things i've noticed in difficulty: -lack of strategic resources. once i finished teching iron working, i bee lined my settler to the closest iron node which was quite a distance away from my capital. i couldn't build any horsemen and knights because i didn't have any horses in my control.. i was only able to pump out some cavalry when i traded some of my luxury resources for horses. also couldn't built any cannons because i lacked saltpeter for awhile and had to use trebuchets to siege the weakest neighboring AI CIV. -i was very far behind in the tech race: by the time i reached pre-industrial age, everyone was more or less in pre-modern age. i let the 2 big nations fight it out for a long time, russia and india giving them both right of passage; luckly they left me alone. i had to relegate to getting new cities by using a settler when either russia or india took over a city because in doing so it made their local cultural influence smaller. i was trading as much tech as i can to keep up the best i can, but i was just so far behind everyone. i wasn't able to build any great wonders and therefore i wasn't able to get a golden age at all. i think this hurt me. i switched to republic as soon as i can when i had a few 6 towns ad 7 cities and never switched back. i've also noticed the TOW Infantry feels like a very strong defensive unit that the stats shows as 12/14/1 with 6 bombardment. even when attacking with my modern tanks with them in size 6 towns w/o walls, or when they are not on hills or mountains, it was 50/50 that i would win. also couldn't get my 1st army from an elite unit until late in the game when i had modern tanks. i have saved files to share.. but i don't know what i could have done better. manhattan project was built by another nation, and babylon which was isolated with 2 medium sized islands, they built they UN and were going for a space victory. using nuclear subs with nukes was the answer to really hurt them.
