We're already nearly 24 hours into the 72 hour* "Free Xbox Live Gold Weekend" sponsored by the telco overlords at Verizon. This is a chance for all you 360 owners out there who managed to save up the $400 (or, more likely, $300) to get the thing--but didn't pitch in for a Gold account--to get a taste of what you're missing. I recommend you start by downloading some multiplayer demos, like GR:AW or Battlefield 2, and rocking them out multiplayer over Live.
*It's notable that Verizon and Microsoft chose this weekend over all others; considering we're going to lose an hour due to Daylight Saving's Time "springing" forward, this is really a 71 hour "Free Xbox Live Gold Weekend." What are we not supposed to look in the mouth again?
