You know looking at the pictures, the art direction just doesn't scream Nintendo...and the width of the play board is too small...or the characters are too big to really work for my tastes, so I think it could be fake.
But, it is a hell of a good fake if it is fake. Really, alot of time was spent on creating 4 screen shots of a game if it is fake.
The sad thing is...I really hope this is real, and I hope that it is good and the graphics are just bad because it is a Nintendo C team working on it...because I really like Wario's Woods.
