The Nintendo 3DS XL isn't in stores yet, but website 3DS Buzz is already offering one as a prize in a trivia contest. On Saturday, July 21 at 19:00 GMT (that's 3:00pm ET / 12:00pm PT) the site will host a quiz contest covering thirty questions about video gaming from the 1970s to present in which one of the oversize handheld units will be given away to the participant with the most points once the system is released next month. Head over to the site to read all the details, and if you participate, be sure to tell 'em that Press The Buttons sent you. If you've been a PTB reader for a while then you know how much I love gaming obscurities, so if you've been paying attention to my ravings on Aero the Acro-Bat and Bionic Commando, then you might have a leg up on the competition if those topics should come up.  Knowing all of this stuff has to pay off eventually, right?
