Who among us can't remember crowding around the class Macintosh to watch one lucky kid at a time try to make the journey west to the pixelated promised land in Oregon Trail.

Oregon Trail is back, this time from mobile mega-developer Gameloft, in an updated version for your Android phone or tablet. And it's free.
