"First of all, I tried out Child of Eden, the polygon murder spree from the creators of polygon-murder-spree Rez, essentially a rail shooter about the internet being under attack by an amassed army of forgotten screen savers. Certainly a spectacular display, but even a cosmic dance with a hundred large-breasted space fish loses something when you have to replay it for the third time because you weren't clear on what you were supposed to be doing. Yeah, I know, game, "Use my left hand to shoot down the purple projectiles before they hit me." Now in what specific way did you envision me using my left hand, 'cause that could mean anything from waving it to sticking a bowling pin up a gorilla's ass. Eventually I figured out that "use" meant, "Do the same thing you do with the right hand to use your normal weapon, but keep your right hand pinned to your side because I might think you're trying to strangle me and go in to a panic." And even then, the usual delay motion sensors have before registering your action led to several frustrating game-overs. And every now and again, the game would pause itself right as it was getting excited, because it assumes that any ambiguity of motion on your part means that you have suddenly been abducted by space monsters. But doing panicky improvised t'ai chi to amuse graph paper is not gaming. It's more like therapy for geometry-phobics."
