Video Game With Some Value

While Washington is aflame over the latest scandal over the video game Grand Theft Auto, which IMHO was pretty inappropriate for most kids before they found this little easter egg, this little game comes back to remind us that computer games CAN be fun, educational, and addictive.
The only warning I'll provide is that the game can get really addictive really quickly. Other than that it's just good clean fun.
