Tactics for the Swamp (Fortress).

You need to find a chest with 2000 gold and a bit of gold on the first day (although, if you find Bron with seven basilisks, a Dragon with thirty gnolls, or Vistan with fifteen lizards in the tavern, you buy a hero instead of building a prefecture)... and then a lot of wood... it's quite challenging... but in the version without wyverns, the development in the first week goes through monsters, and only then you invest in gold if you have enough wood for the market/smithy/castle...

P.S. Oh, I'm writing this and thinking maybe I should launch the third game and play, because I haven't played it in a year, and even less after the release of the fifth game...
