DC is way better as an actual game.
At first, DH/MWIII seemed like everything I wanted in an adventurey Monster World game, in that it seemed to be a larger evolution of WBIII/MWII with nice 16-bit aesthetics.
But one play through was all I could handle before it became tedious and boring orverall. The play progression/overall design just isn't very good.
Where as DC/WBIII/MWII is the pinnacle of thre MW series because of the great layout/progression. It still looks and sounds great on any system, but its the gameplay and real fun that everyone loves it for.
