The refurbished version from GOG is a new product with NEW features and qualities (which costed time and ressources to GOG): they seached and talked with the rights holder and allow you now to purchase DKII again, they offer real product support again, they tested the compatiblity for different newer hardware and software platforms and created and included comptiblity fixes, also they provide a digital download which can be seen as "cloud" backup.
