It's a silly thing to do. Diablo copies a lot from roguelikes. In fact, it is considered the first commercial roguelike.
"Diablo by Blizzard is considered by many to be a commercial roguelike, a roguelike that was graphical and real-time. Developers Brevik and Schaefer had in mind a graphic version of the "old Unix-based games". Eight months into development, the decision was made to make the game real-time as opposed to turn-based. Diablo is by all accounts a Roguelike, but with graphics and real-time gameplay."
