A few years back, you had the ability to actually try things before you bought them. That is, in the video game industry. Retail stores still feature demo "kiosks" where you can play on a console for a few minutes, and try out a few of the games they've got on some kind of demo disc in the tray, but for the most part, you're at the mercy of other means entirely to find out whether or not you want to buy a game, or even the hardware itself. For Sony, that's just not going to cut it, so they're planning a huge marketing push to get their PlayStation Move into the heart and mind of all potential purchasers. And what's a better way to do that then let them play it, right?
