Saw on a deal site that MAG is $1 used right now at Gamestop, dunno if it's temporary or they're just trying to clear them out, new copies are still $20. I walked into the Gamestop next to a Chipotle we went to for dinner, asked if they had any copies, and the guy was like, "Hmmm, let's see...32 actually."
So I bought 3 copies, 2 for me and my son to try out online together and another copy for a friend.
If $1 doesn't scream, "Time to jump in," I don't know what does. Of course, $1 might also mean, "They're about to take these servers offline,", but I like to think about a glass half full.
