Whenever I play Rock Band, I always use my 360 Guitar Hero 2 controller. Reasons include a functional strum bar, a solid design, and consistent functionality. That's a nice thing about the Rock Band/Guitar Hero divide, for as long as they undercut each other, those mics, drums and guitars are going to work together, by and large.
Well, I had a chance to speak with the Creative Director of DJ Hero, FreeStyleGames's Jamie Jackson, and I asked him about his game's proprietary controller. DJ Hero plays very unique, after all. Would his turntable be able to work with other games in the future, much like Guitar Hero/Rock Band?
"No," he says, after a short pause. "DJ Hero is DJ Hero. If someone needed to use our controller, then they would basically have to rip our game off."
Of course, to be fair, the two DJ games currently announced, DJ Hero and Scratch: The Ultimate DJ, are very different products, with very little shared between the two. It would be nice to not have to buy a whole new slew of peripherals, however, which has the potential to limit sales for both games.
