The Wii U has plenty of new software on display at E3 2012, but Nintendo’s new system also has its share of ports as well. Today at E3, I played Batman: Arkham City Armored Edition and Ninja Gaiden III: Razor’s Edge, a pair of action games that presently exist on platforms you probably already own. But how do they play on Wii U? What benefits does Nintendo’s new game pad bring to their experiences? And, more importantly, do they really work?
