And it's not easy. You have to get over 80% in order to get a completion for each song, and some are virtually impossible until you're more familiar with them. Because the drum itself doesn't move on screen, you feel completely in control, and the play is intuitive. Once you've properly got into a groove, you can feel yourself relaxing, and your moves becoming fluid - you're allowed that extra breathing space for a few seconds where you can forget, or pretend to forget, that you're playing a game. Now, we're not idiots - two teeny bits of plastic aren't the real thing, but for a glorious few seconds of bashing joy, it's the closest, most fun thing we've got.
