I recently got a new Xbox 360 and I was wondering if there is a way to move my Steam games (specifically Assassins Creed, Half-Life, Portal) to the Xbox hard drive. Perhaps I could redeem them for a hard copy somehow?
Games do NOT transfer from Steam to Xbox as a legit version. Once you purchase a game from Steam, it is only available on Steam.
Even if you did move your games over to your Xbox hard drive, you would still need a hard copy disc that is specifically made for Xbox to run the game. There are ways to burn Xbox discs but they are very illegal.
