Being 2-D partly prevented Muramasa from coming to Ps3/360
Muramasa: The Demon Blade almost came to an HD console instead of the Wii, states Vanillaware founder George Kamitani, but because of high dev costs and a 2-D game being hard to publish on the HD consoles, the decision was made to come to Wii.
