Novels, Lore Books, Movies, Tabletop RPGs, (THE)Video Games, Card Games, Card Game Video Games - (Hearthstone), etc.

Blizzard seems to have developed a new strategy for the company: The more types of media you sell your product in, the more new players - who might not even have cared abut a video game before a movie adaption for example - flock to your video game to experience things first hand.

What do you think - Is this media abundance good or should they focus on WoW only for the story of Warcraft?
