1 thing I don't like (from an aesthetic perspective) about the above ruleset is the advisers being able to move diagonally within a single 3-by-3 layer without advancing or retreating. Logically (if the palace is made of a plus sign extended upwards, which it would be if you think about pieces being on 6-way intersections rather than in cubes), the adviser would be outside the palace when it is halfway through the movement, so I don't think that should be allowed. Also, the official xiangqi rules say "Advisers may advance or treat", so they would not be allowed to move without advancing or retreating. This quote could be interpreted as just a description of what happens in the 2-dimensional game and not a separate rule, but even then, my previous point stands about the adviser being outside the palace halfway through the movement (assuming it follows a straight line). I guess you could see the palace as a (45-degrees-turned) square prism in order to refute that argument, but seeing it that way seems a bit strange.
