The only problem for Ninja Gaiden is even if you're a Wii U early adopter that's hell bent on getting something "matoooor", it seems like Black Ops 2, possibly Zombi U, and even year old ports of things like Arkham City are far better games than Ninja Gaiden 3.
Maybe Tecmo should've ported Ninja Gaiden 2 instead with Ayane and other features as that seems to be a better game from its foundation.
Nice try Tecmo, but for $60, I'm forced to cancel my pre-order on this game to be honest. Will be getting something else, probably ZombiU.
