Rice Paddy game

This game originated in China where these two guys wanted to feed their family.
The game where there are two rice paddies side by side. The goal of this game is to grow and harvest the rice in the fastest time. HOWEVER, there are rules.
1.You may not steal the opponent's rice to keep your family fed.
2. You may not use growth hormones because that will make your rice look like crap.
3. You may not kick the mud barrier separating the rice paddies in order to ruin your opponent's rice paddy.

Whoever wins gets all the rice that the player and opponent has grown.
