Depending on who you ask, video games are either a healthy or unhealthy habit.
One of the first games I ever played was a computer game in elementary school called
Oregon Trail. Basically, you traveled across the Oregon Trail as a settler, bought supplies and provide for your people. It doesn't sound like much fun today given the way
technology has advanced, but back then we were glued to it like it was
Halo 2.
Anyway, here's a cool
interview with the developer of Oregon Trail. At least, I thought it was cool.
