Best trade strategy: buy max rice at good price, sell in another town, battle a pirate, go back to town you sold the rice to, and it will be at an extremely low price. I do this in between 2 towns for good money.
Love the developer's response - "Developer response from kanoapps
Good idea, would perhaps stop a lot of players from adding the game, selecting a character and then giving a bad rating / comment without really giving it a real try/playthrough." Lol
We try to have a sense of humor and think we don't do that bad :)
