Here is a theory i have been working on before cnc1 and ra2 there was DUNE cnc1 and ra1 are on the same engine as DUNE. before cnc2 and ra2 there was DUNE 2000 cnc2 and ra2 are on the same engine as DUNE 2000. before cnc3 and ra3 (maby) there was emperor battle for DUNE cnc3 and ra3 (maby) are on the same engine again. so im thinking that the dune games are sort of a test of the game engine before they release the big money maker games like cnc and ra? please tell me what u think
