Matt is a fair-minded reviewer and lover of games of all platforms and types, big or small, hyped or niche, big-budget or indie. But that doesn't mean he will let poor games slide without a good thrashing when necessary! 
How do I link my Gamertag and Windows Live account. All I ever get is a message saying I need to link them, but no instructions on how.
Unfortunately I have no clue either lol. I really don’t do much with XBL or online play in general so I’ve never done this. You’d think they’d provide instructions on the website since it’s a requirement to compete. The rest of the VGB gang does more online than I, so someone here probably knows. I’ll see if I can find you a solution.
I believe you can just head on over to http://live.xbox.com/en-us/default.aspx and log in with your live account.
Actually it’s been so long since I’ve done this that I don’t quite remember how other than following the steps that MS gave.
