Classic Game Room HD reviews YOSHI'S ISLAND for Super Nintendo SNES from 1995! Also known as Super Mario World 2, Yoshi's Island is an amazing 16-bit side scroller with incredibly deep gameplay with intelligent design that separates it from the normal side scroller. You play as a variety of Yoshis (I didn't know there was more than one!) who are trying to rescue baby Mario's twin brother Luigi! Luigi was kidnapped!? Amber Alert!
