Drug Wars was a classic game that has been constantly re-made and re-imagined since it’s first version on DOS (do people remember what DOS was) in 1984. Basically you assume the role of a drug dealer and need to make trades and deals to make more money and avoid the bad guys. It was and is wildly popular.
What if you apply the same simplicity and general ease of understanding the game play to develop a game that taught kids how to share better.
The more they give, the more they get. Seems like a better lesson than drug arbitrage.
