World of Warcraft. Before the game was released we only had regular Warcraft and they were very very good games. The thought of being able to make your own hero in the Warcraft universe was a thought that appealed to a lot of gamers. I know a lot of people don't particularly like WoW but think back to before it was released and remember how excited you got. The concept of a world of Warcraft is hype in itself.
Also, The Rain Slick Precipice of Darkness, because that is a pretty good name for a game.
