Street Fighter II is widely acknowledged as the premier fighting game of its era, due to its game balance with regard to the timing of attacks and blocks, which was unparalleled at the time; and due to "special moves" in which experienced players could execute complex fighting moves by moving the joystick and tapping the buttons in certain combinations. The game featured a six button layout, with punch buttons consisting of 'jab', 'strong', and 'fierce' and kick buttons consisting of 'short', 'forward', and 'roundhouse', in ascending order of strength. This was not new or exclusive to fighting games, but the way in which the game mechanics utilized them was revolutionary.
