Back in 1991, Capcom released its 2D fighting opus Street Fighter II, and in the years that followed a number of competitors brought their own fighting games to market. SNK was by far the most prolific rival, and while some of its games, such as Art of Fighting, innovated upon the formula they were inspired by, developer ADK created World Heroes for the Neo-Geo, a series that was content with completely ripping off from it. Nearly 16 years after the original hit the arcades, all four World Heroes games have been released in a single compilation title, but despite their flawless porting, this series is best forgotten by all but the most hardcore of fans and collectors.
