    In a 2D game Y is up. Going from 2D to 3D would make sense to add another dimension forward to account for depth.

    However if you start with a map of a 3D surface then North is Y and East is X you’d add Z to account for elevation like everybody making maps would.

    I guess it depends on how you look at it.
