I have. Your on the right track, but there's some things you could do to improve it.
First off, screw the farm. You won't need it. Your going to rely just on cows. Your going to need to last on hunts untill the 4th/5th age. If you can last untill the 5th age, that's best. (But most maps you can't do that) If all else fails use your market to get food to advance/make cows.
So when you know your not going to be able to hunt eventually, make a livestock pen and make 10 cows. Then send a villager to your allies base and make another livestock pen. Have the cows sent to where they'll become your allies, thus avoiding the 20 pop max. Make anywhere from 50-80 cows that way, and have your ally send them to your base and have them gater on more livestock pens.
If you don't have allies, you'll have to mix in sheep too. But keep in mind, if you used just sheep you'd end up with the same eco as using farms.
Later in the game when you start getting low on cows, you'll have to mix in sheep too. Unless you want to hassle your ally with sending you more.
Benefits to this:
1. I can get 5-10k more food with 15 villagers, 5 less than I would use on farms.
2. This allows you to put 20-30 villagers on gold. Getting you much needed gold.
3. This only requires the livestock card, so you can get all those plantation cards asap, since you won't have to use those 3 or so cards benefitting farms.
I used to get 1350-1450 with dutch, now I can easily get 1600+ at the 40 minute mark.
Oh I just realized this wasn't necessarily for a nr40 game.
