The Wood Industry is somewhat/largely unbalanced under certain circumstances.
1. Embark with as many Steeloak Saplings as possible next to a volcano, or find/create magma.
2. Channel out an area of 4 10x10 farms for Steeloak Saplings, and 4 5x5 farms for your food crops.
3. Mine for some Minerals, sell them at Ore Trader.
4. Build a Carpenter Guild. Upgrade to Level 4.
5. Build a Trap Merchant. Buy 4 Bronze Sawblades.
6. Build Sawmill and Exotic Wood buildings (4 of each)
7. Dedicate workers to them, then create your forges. Make Knuckledusters (worth 2 Vouchers for 1 Steel Bar!)
8. Sell Knuckledusters for Vouchers, then sell Vouchers for coins.
Bonus: Equip your farmers, sawmill people, exotic woodworkers, smiths and merchants with Rocket Boots from the Gnome Merchant. You are now hyper efficient and can convert Acorns to Coins at lightspeed.
You are now rolling in coins, and can easily approach a million.
