Jeez, I'd completely forgotten about RD. And Ghost Hound, come to think of it (should really finish that). Though I'd argue RD was in the same category as Ghost in the Shell, where the 'virtual' world and the physical world were so intertwined and inseperable that they could both be argued as equally 'real' and valid (or rather, that reality were composed of both and splitting them up and perceiving only one would only be partially perceiving reality).
