I have recently discovered that it seems to be the general consensus that "beat 'em up" is a term only used to describe scrolling fighting games where you fight multiple enemies, such as Streets Of Rage or Golden Axe, and not your one-on-one Tekkens and Street Fighters etc. I have had this the other way round all my life, based on how the Official PlayStation Magazine used the term. Have I really been wrong all these years?
