Etrian Odyssey IV: Legends of the Titan review. Classic Game Room presents a CGR Undertow review of Etrian Odyssey IV: Legends of the Titan for Nintendo 3DS developed and published by Atlus. Etrian Odyssey IV: Legends of the Titan does the player no favors whatsoever. Here's some paper, here's some pens, make your own map. And for a certain kind of player, the kind that thrives when the pressure is on and is motivated (not discouraged) by a near-insurmountable task... for a certain kind of player, it's exactly what an RPG should be. Featuring a deep and thoroughly customizable skill system, several distinct classes, airship antics (which may or may not include dragons), and an enormous challenge, Etrian Odyssey moves into the third dimension with authority. This video review features video gameplay footage of Etrian Odyssey IV: Legends of the Titan for Nintendo 3DS and audio commentary from Classic Game Room's TJ.
