Mortal Kombat
The Mortal Kombat characters played virtually identically to one another (with the exception of unplayable bosses and hidden characters). Whereas other fighting games had characters with considerable differences in speed, range, height, normal moves, strength of normal moves, walking speeds, jumping heights and distances, and so on; characters in Mortal Kombat differed mostly in their special moves and finishing moves. Essentially this led to increased importance placed on special moves, as they were the only unique part of most characters.
