Full disclosure: I'm way too far into old world
I'm doing something I started way too late in Civ. I'm trying to take the game slow and learn it as much as possible before progressing to higher levels. I agree with you 100% that there is
a lot going on. There are a lot of subtle mechanics to this game. To that end, I am playing each Leader from the lowest level (i.e., "The Able") on up. Oh, and going full nerd as well keeping statistics on a google sheet.
I've never had to go 200 turns to win, but I am not playing on larger maps (yet), just whatever the default size is.
Able
- Fastest victory: Greece/Philip at turn 72, Double
- Slowest victory: Carthage/Dido at turn 169, Ambition (I think this was the first game I played)
- 8 victories: 3 Double, 2 Ambition, 3 Points
Just
- Fastest victory: Rome/Romulus at turn 82, Double
- Slowest victory: Egypt/Hatshepsut at turn 159, Points
- 8 victories: 1 Double, 2 Ambition, 5 Points
Good (so far; I've only gotten through two games)
- Fastest victory: Greece/Philip at turn 89, Double
- Slowest victory: Babylonia/Nebuchadnezzar at turn 133, Ambition
- 2 victories: 1 Double, 1 Ambition
There are very few youtubers doing game play throughs, and the ones that are on there are laughably bad for the most part. I've been advancing on my own.
Regarding water crossings, you have to have a ship (e.g., Bireme) in the water between where your troops are and where you want them to go, and have that ship anchored for 1 turn before your units can cross. As ships advance, distance that can be crossed does as well. There's also a ship promotion that extends distance as well, although I can't remember it off the top of my head.
As far as domination goes, I haven't come close. The old world AI is remarkably good at attacking and defending. In one of my wins I ended the game by taking back a Legendary city from Assyria (who I've found can be a real PITA).
I think this game is just as addicting as Civ, so fair warning if you do jump in. I've found myself paying more and more attention to the characters and their traits to optimize governors, generals, ambassadors, etc. I think this can be very helpful.
One thing I'm trying to do, but haven't had the right Leader/trait yet, is to imprison a member of each Family as a Terrifying Leader. Apparently that skyrockets Family attitude.
