The one thing though that I've heard the fewest complaints on is the lore. The story, the background, the characters and their development, the progression of the game through the various acts; this is where I've found the least combinative whining of every forum throughout the games life.
I don't know about you, blizzard, but I think that means something.
I think that means you have the ready made material for a minimum of twelve movies; one for each act (expansions included) covering the three existing games. You have the plot, you have the cast, you have the scenery and the mood; there's an existing fan base large enough for you to recoup your investment if not make a decent profit. Cinematic blurbs exist to give you direction, models sit in digital archives to give you cast and you've built a massive company around WoW and the release of D3 to offer you the talent needed to built this into an epic worthy of being a household name. I've only two questions:
What's holding you back, and who will post signatures after me to convince you to stop?
