the 3D Castlevania game if something like it was released on N64 bitd?
Obviously games from previous gen were originally built with a 2D framework in mind and the successful games excelled at it, but I felt like a lot of people wondered how their favorite games would jump to 3D when the new consoles showed us they were capable of 3D.
I think this demo is a good starting point. If they put in some engaging first-person platforming like Metroid Prime did on the GC, it could have been fun.
