Words: Dan Stapleton, PC Gamer US:
''Loosely based on the popular web comic Penny Arcade, this new episodic series kicks off with a six-hour game, cheekily subtitled On the Rain-Slick Precipice of Darkness. The action follows your custom-built avatar (and his disappointingly limited wardrobe selection) and early-20th-century versions of heroes Gabe and Tycho as they investigate paranormal goings-on in the city of New Arcadia. It's a bizarre tale that's completely unrelated to the comic's setting, but bizarre is what Gabe and Tycho do best. On the plus side, the game doesn't require any prior knowledge of the comic characters or their back stories, but, on the other hand, it doesn't take advantage of the comic characters' back stories, either. The writing has the same witty, often-crude edge to it, and Gabe's thick-headedness remains a perfect foil for the esoteric Tycho. If you appreciate Penny Arcade's humor, you won't be left wanting for laughs here.''
