Put simply, NARC is a mess. Every time it starts to show a little potential, it blindsides you with a nearly unplayable mission, amazing camera failure, or a flat-out boring sidequest. [May 2005, p.112]
Aside from hearing what decently cast voice acting sounds like and hearing Michael Madsen give an excellent performance in 6-10 hours of bad gameplay, there's absolutely no reason to touch this game, even at $20.
Everything about the game feels clumsy. The graphics are mediocre, the gameplay is middling and repetitive, and the completely shallow glorification of drug use is either appalling or just plain stupid.
