Released by SNK in 1990, the NeoGeo MVS (Multi Video System) arcade hardware and its home counterpart, the AES, boasted hardware that could handle massive sprites, fluid animation, and CD-quality audio. Games like Metal Slug , King of Fighters '98 , Samurai Shodown II , and Garou: Mark of the Wolves remain benchmarks in game design.
