Maybe you'd like to share some of those mistakes, specially the strategic ones, so that other people can learn from your experience.
ha...I'd planned on coming back to post more as I usually do. Just my initial reaction to slogging through to the finish and submitting literally 1 minute before the deadline, then collapsing in exhaustion.
Disappointed in my 1800ad dom win, which is just ridiculous on this map and settings. The naval aspect posed a bit of a challenge and that is exactly where I failed.
It was clear very early when my 2 scout workboats surveyed the map that a nice Dom date was achievable here. I Oracled Feud while Hannibal contributed constantly to my Worker Relief Fund. I think I built maybe 1 worker if any the whole game. Stole at least 10 from him before wiping him out.
I really looked forward to some uber-LB stompage. However, my key failure was not thinking at all about the naval conundrum while conquering Hanny and settling the landmass. What it boils down to is that I settled only one and somewhat poor production coastal site on the eastern shore. Same in the north. Furthermore, I kept Carthaginan cities that should have been razed and resettled as coastal. The result was seriously nerfing and delaying galley whippage and, thusly, losing a good window to take out the Civs in the East.
It went downhill as well, as Cyrus just sat there, after capping Peter, building unit after unit. Bizarrely, he sent a lone galley up to Vicky and Dow'd her with absolutely no units. He kept all his units right next to me in Susa on the coast. I actually thought he was going to attack the Incans and waited for that window. Anyway, had to take the plunge and took heavy heavy losses. Winning was never and issue, but it was a slog. I would have been better of just settling in for a nice peaceful win here.
Anyway, lesson learned, that I should have learned ages ago, is you really need to think about the map in terms of what you are trying to achieve in victory.
