I am no fan of horror or thrillers. It was years before I could sit through Jaws and I've never watched more than an isolated chunk of any of the Alien movies. And yet, I do love the adrenaline rush brought on by the imminent peril I feel in certain video games, knowing that something unstoppable is on my tail. My favorite part of Metroid Fusion was the SA-X, its relentless search for Samus, and how much tension would build up when it entered the room I was desperately hiding in.
