Comapiring Mortal Kombat to Street Fighter is like compairing a tricycle to a Harley Davidson.

SF is better without question. Play the two. SF has better characters, better story, better graphics, better sound, and better gameplay. MK is too much of a newbie fighter, the only people that appeal to it have ADD and can't memorize button combos containing more than three buttons.

Plus Street Fighter has Ken, the biggest ladies man any video game has ever had.
