Sure, why not
The PlayStation 3 and Xbox 360 ports of Ninja Gaiden 3: Razor's Edge are due out on April 2, but before full release, Team Ninja has put out a demo for this updated take on the action title. The demo itself features gameplay sections for Ryu and Ayane, and any Karma and Ninja Skills earned will be transferable to the full game.
Despite passing on anything and everything Ninja Gaiden following Ninja Gaiden II, I feel oddly compelled to grab this demo in order to get a better perspective on Ryu's latest exploits. And even if it goes unused, the save transfer feature is reassuring.
