I have also not really wanted to go back to 2D games; not because of the graphics, but because of the actual game mechanics of a 2D world vs a 3D world. Case and point: Dwarf Fortress is “3D” without being 3D. The world itself is three dimensional, even though you only are presented with a 2D slice of it. Other games have replicated Dwarf Fortress’s gameplay in 3D graphics, yet are still otherwise just two-dimensional with just 1 plane of operational space.
