My tactics for the French is this.
1a) Gather all the resources you get from your homecity.
1b) Send Explorer to find and gather easy treasures/send native scout in opposite direction.
2a) Train more Coureurs.
2b) Put Coureurs to build market and research the first tech for improved hunting (hunting dogs?).
3) Put all Coureurs to hunt closest animal.
4) Upgrade wood-collection ASAP.
5) When it starts to become a bit crowded, I send all Coureurs to chop wood.
6) Continue to train Coureurs, build houses when necessary.
Somewhere around here I've sent for more Coureurs.
7) When I've 800 food, I advance to the 2'nd age.
Somewhere around here I send for the card for improving the trading posts.
8) When I've started to research the 2'nd age, I gather 200 food more, and then put all Coureurs to chop wood.
9) In the second age, I start to build as many trading posts I can, along the trade routes (but only AFTER the improvement card has arrived), upgrade to stageroach ASAP.
10) Build barracks and train 10 crossbowmen, and 5 pikemen.
11) Keep training Coureurs.
12) Upgrade food and wood gathering.
13) Train more crossbowmen and pikemen.
14) When I've about 50 soldiers in total, I attack, this is within the first 6-8 minutes depending on treasures and such.
15) Within about 20 min I've won.
Harder battles,
16) Keep doing this, and develop coin gathering with your trading posts.
17) Keep advancing in the ages, and finally, train musketeers and Cuirassier.
