1up.com is running a piece talking to six professional game developers, where they discuss the possibilities and possible pitfalls of the Nintendo Revolution. From the article: "I don't think it will be difficult at all to make full length titles for the Revolution. First of all, Nintendo has hinted that they will provide an add-on for the controller that will mimic a "normal" controller, like the GameCube's Wavebird controller. Second, as long as the device is light, movement based input is not that tiresome. I have used a gyroscopic mouse for many years, and can successfully play many games with it. I would presume that games specifically tuned for the Revolution's controller will be easy to use for extended periods of time. As a bonus, gamers who play that long will end up with impressive looking forearms!
