When television shows go on hiatus, they frequently return to the airwaves with a storyline that reflects the passage of time. The protagonists of Penny Arcade, on the other hand, make a point to mention the fact that the four years that have elapsed between 2008’s Penny Arcade Adventures: On the Rain-Slick Precipice of Darkness Episode 2 and the upcoming Episode 3 amounts, in-game, to all of a week. Comparing the two episodes, though, you’d be forgiven for thinking Episode 3 actually shattered the limitations of linear time and came out years before Episode 2 — about 15 years before, to be precise. Where the first two installments of Penny Arcade’s game series were contemporary-looking 3D adventures by Hothead Games, Episode 3 leaps backward three hardware generations to resemble a 16-bit RPG.
