As educational video games intended for children go, MECC’s The Oregon Trail is already bleak in its depiction of life in 19th century pioneer life in America. After all, this was the software that made a pop culture byword out of “You have died of dysentery.” But even The Oregon Trail had to sugarcoat things a little for elementary school students. MECC kept in the buffalo-shooting, river-fording, and bead-trading, but the company left out the whiskey, the wild parties, the cross-dressing, and the children crushed beneath wagon wheels. Fortunately, for the now-grown Oregon Trail fans of the world, Vox presents its own R-rated Oregon Trail for an adult audience hardened by years of violent cable TV shows and internet pornography. This is not a playable game, by the way. It’s a four-and-a-half-minute presentation video with some 8-bit-style animation. For those who want a quick, quirky history lesson, it gets the job done.
