GamesRadar - Mechanics: the rules and parameters by which we live and die in the virtual realm. They're often meant to empower. Activating Bullet Time and taking down a room full of bad guys in one fell swoop is an awesome feeling, as is blowing up a building while a legion of enemies take refuge inside. Other times, mechanics act as roadblocks meant to prevent players from becoming unstoppable gods. You can only activate your super powers for a few seconds before you run out of energy and need to chug a magical potion to replenish your strength.
