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.
Yes, but please just make it follow the right hand rule...
Which one?
(Technically all the same, I know).
The first? I dont know... They all look weird since the finger axes dont intersect properly.
