But at some point, the heretofore non-MMO gamer decides to take the plunge, whether out of curiosity, or the constant browbeating of his more evolved peers. He might give World of Warcraft a spin, considering how popular it's grown. Or he'll jump into City of Heroes out of love of the comic book medium. Or, being a Tolkien fan, he'll download the Lord of the Rings Online trial. Suddenly, the scales fall from his eyes, he renounces all worldly goods, and becomes one of the converted. Oh, he might still play the occasional single-player game, but he'll never give up his guildies.
Which MMO made you see the light?
