A (Possibly) New Secret Level Idea

[:1]What if the secret level was a series of rooms in a dungeon, filled with monsters and notable NPCs from the three games. After you kill each NPC, they say one of their most memorable quotes from the game.

My original plan was all of the NPCs in one room, without monsters. However, I figured that it would be too hard to hear all the dying quotes from the NPCs if you could, say, kill two more in a single cleave, etc.

And after all Deckard Cain made us go through, it would be fun to pay him back. And the final NPC would be Tyreal, accompanied by rainbow coloured unicorns.|||Oh dear....lol. I think it would be fun to see the Drunk from Diablo 1 :P
