Pre-ordering will net customers a swanky wallpaper or PlayStation dynamic theme in addition to the game itself, which has been mostly unavailable for the last 16 years. The remaster includes a re-orchestrated score, HD graphics, redone controls (alongside the original tank controls, of course), and developer commentary.
I wish more developers released commentaries for their games alongside HD remasters. That'd be swell.
Grim Fandango Remastered will release January 27 for PC, Mac, PlayStation 4, and Vita.
