Metro launched fine for me. Make sure you click yes on the Microsoft window that asks for permission to give the game your info or whatever. Sometimes you have to alt tab to it. Only have to do it once tho.
But yea the game is pretty boring. I played if for about an hour and by the time all the cut scenes ended, the gameplay felt very slow.
