Ok, so I just bought Halo 2 GFWL key. Can I use this key with Halo 2 ISO file from torrent since I don’t have phsycal copy of the game or is that not allowed and could get banned? I have X360 and Live account which I would like to use to play Halo 2 to get PC achievements and really don’t wanna lose it cause of one game and it’s achievements.
You can do that. So long as you own a license, you can do that legally.
