Wonder Boy in Monster World review. Classic Game Room presents a CGRundertow review of Wonder Boy in Monster World, part of Sega Vintage Collection: Monster World for XBox Live Arcade. Oh, the difference one word makes. And, well, a couple more iterations of the game itself. This is the fifth Monster World game, though even it would refuse to tell you so, and it revisits the basic mechanics of Wonder Boy in Monster Land, but with all the grindy arcade bits taken out for you. How convenient! Sporting an overhauled inventory and magic system, bigger bosses, cuter sprites, and the occasional ocarina lesson, Wonder Boy in Monster World shows us just how much more interesting stuff you can pack into 8 more bits. This video review features video gameplay footage of Wonder Boy in Monster World for XBox 360 and audio commentary from Classic Game Room's TJ.
