Sony: PlayStation Now Will Require a DualShock Controller
 

This would be one of those times when Sony should say 'oh, by the way'…..you're going to have to have a DualShock controller to play games'. Instead of addressing the control issues head-on, Sony opted to require the use of a DualShock controller instead. That may sound like Sony cashing in by requiring you purchase an expensive games controller, but if you think about it, it makes a lot of sense for gamers, too.
