'Witcher 2' loses something in translation

For PC owners, the “Enhanced Edition” of “The Witcher 2: Assassins of Kings” means four extra hours of gameplay. For those of us whose computers can hardly run “Minesweeper,” it means one of the most acclaimed role-playing games of last year can finally be played on a regular gaming console. The Xbox 360 version proves “The Witcher 2” is just as good as the mouse-and-keyboard set said it was — but, with an unavoidable change that’s distinctly not an enhancement, it won’t cure anybody’s PC envy.
