There is some serious confusion over when exactly Nintendo's Super Mario Bros. was released in the U.S., and a new Gamasutra feature explores that mystery. The game has always been pegged as having hit the U.S. in 1986, but an abundance of evidence points instead to 1985, thanks to some dynamite investigative reporting from Gama's Frank Cifaldi.
The three-page feature chronicles Cifaldi's exhaustive search for some sort of "official" U.S. launch date for the game, with anecdotal reports, publicly recorded evidence, and, in a fun twist, a last-minute anonymous tip. If you have any appreciation for video games and where they come from, it behooves you to read through te feature and educate yourself. As Cifaldi points out in his conclusion, "If this is the state of video game preservation in 2012, 50 years after Spacewar!, we're in trouble."
