I should add one thing here: no theory that is consistent with special relativity can work on a discretized spacetime, because of the structure of the Lorrentz transform. If a distance appears to be 5 Planck units to you, it will appear to be 2.5 Planck units to someone moving at half the speed of light relative to you in the direction of that distance.
