I have played this a few times. At first it is fun, but it is basically
just the same thing but in another dimension. What I mean is that the
symmetry is kept, but this in the end adds no new value to the game. It
only makes the game more complex and longer.
I noticed that the creater added some changes. I played it under the
first rule set when it came out.
In the end I did not care for it. When I think of 3D board games. I
think of their being pieces which can move between planes, and those that
cannot.
