Reader BenDoverx reports that the "region-free" copy of Ghost Recon: Advanced Warfighter he bought for a paltry $41 (including shipping) from Play-Asia.com works like a charm on his American Xbox 360. He even posted a pic of the "thanks for shopping" note as proof of purchase. Asian GRAW must be selling like a charm too, because the price has been jacked up $7 since I first mentioned this cheap ass way to save a few bucks ten days ago (although it's still a great deal at $19 off American retail). If you're one of the atheistic types who didn't rush to buy on faith alone, you may commence slapping yourself.
