"Not zombies. Not terrorists. Not bandits, pirates, helicopters, or mutant helicopters. After dedicating my life to research, I’ve determined that mechs are the most fun thing to shoot in a video game. MechWarrior’s mechs, specifically."

"Mechs happen to have more segments than most enemies: a head, center torso, right torso, left torso, right arm, left arm, right leg, left leg, and three equivalent rear torso zones. Eleven discrete targets. But it isn’t necessarily that there are more areas to hit but that they have significance within the game itself. When you’re being circle-strafed by a scout mech in MechWarrior, aiming for the legs is one approach to dealing with them. This act of “legging” an enemy epitomizes the “I have you now” moments the game produces: you get to steal from a light mech what made them special (speed), admire your marksmanship as the enemy limps, and make them experience the anxiety that comes from losing something that made them unique."
