The player is the merchant in the big mine.
But the mine is limited! Also the bank, too!
This world of the game is very dirty.
The mine will be out, the bank will be out all money, too.
And the cooperator have any skill, but they don't work well in that they don't match his skill.
The winner will be that he/she is very careful his/her situation on the game.
