I agree with Mateo360 in that I don't have much confidence returning the game to Best Buy and getting a new one. However, it's hard to believe that the only games having the problem are being sold in Best Buy - what's unique about that? Do they have a different source? Has anyone bought the game from BB and have it work ok? Has anyone bought the game from some other store, or on-line, and had a problem?
Just a couple of thoughts.
Also, maybe Telltale should be getting a little more involved with this problem to determine what the problem is.
And Cyd - thanks for the information.
