The original Red Steel was a great idea that was sadly let down by a terrible control system. While people were quick to blame Ubisoft for coming up with such a half-baked concept, the latest news regarding the sequel might shed some light on why the previous game was so poor: the Wii's control system just wasn't accurate enough.
Speaking to Nintendo Power, Red Steel 2's Creative Director Jason Vandenberghe has confirmed that the sequel would only be playable with the new Wii MotionPlus add-on:
It's a huge risk. We have no idea what the penetration rate for Wii MotionPlus will be. We assume high. We would like it to be high.
Vandenberghe also confirmed that his team had tried to incoporate 'standard' Wii control, but it just wasn't good enough.
