It is not that Bob is wrong. At least this time around. I agree with him and believe me, I would much rather see a movie about D&D than Warcraft. But I have been playing Minis for about 4 years (fuck you, 4th edition) and I have to tell you, there are soooooooooooooooooooo many storylines to follow. There's the Ravenloft setting, Forgotten Realms, the normal setting with the Mountains of Celestia and the Nine Hells, Mechanus, Demonweb Pits, the Astral Plane, the world of Faerun during Spellplague and the Time Of Troubles....
And along with them, there are sooooooooooooooooooooo many characters to follow. Besides the obvious ones already mentioned, like Drizzt, there is Van Richten, Vlaakith the XVIII, Raistlin Majere, General Bel, the liberation of Drows from the clutches of the Mind Flayers, the Seven Sisters, Mordekainen the mage, Mystra and Syric...
You cannot please everyone. I would prefer if it was a story of its own and then we had new minis based on them or something.
