6. World of Warcraft
Now we're talking. World of Warcraft is one of the most recognisable games in history. It's THE online game par excellance. With a story that has been going on and on since 1994, you would think that the developers of the game might want to do something else with the game and maybe some kind of aggressive expansion. I think a series based around the game might be the best way to start. Since this game doesn't have a settled storyline and you are basically running around with your character having adventures, if they make a series based around the game they shouldn't have much problem coming up with a decent story. Hell, why focus on one character? Why not do something else; a different story with a different character every week? Few series have done like that, and if it is well handled, I think a WoW series might be incredibly awesome, as long as they show Leeroy Jenkins, of course.
