If Mirror of Fate wasn't good on the 3DS, it won't be good on consoles. An HD conversion won't change that, nor will a halfhearted effort at fixing a few of the game's mistakes.
By porting its unsuccessful handheld game to consoles, giving it a graphical update, performing some minor cleanup, and slapping on the LoS2 demo, MS is presenting Mirror-HD as an entirely new game. I simply don't buy these types of strategic marketing tricks.
