>When you read the DMC artbook interviews its crazy how much of DMC1 was already there as a RE4 prototype.
You don't even need to read those interviews. The environments and enemies where nearly all design for the game when it was still RE, and then changed slightly or not at all.

And what's more a lot of what wasn't RE in DMC1 came out of Onimusha. Just compare the final bosses of both games.
