I always liked the original U.S. retail cover for Street of Rage because it prominently features the "1 or 2 players at once" wording. This game was released during the height of the Genesis vs. SNES console war, and the SNES had recently seen an exclusive port of Final Fight - however, that port allowed only one player at a time. Sega delivered Streets of Rage with multiplayer capability, and SOR turned out to be the better game - and a true classic of the 16 bit era.
