The game maker is trying to make a point. This is back when China was the only country that grew tea--till later the English stole the plants from China to grow in India. And yes, back then, opium was the only thing English used to trade with Chinese.
This game is way too difficult for me.
If I play as Sheriff or Hunter, I can get to like day 12, but then too little money to upgrade and go on.
If I play as Rogue, I can't even pass day 7.
Is there something I am missing?
