My original two characters in World of Warcraft are no longer around; one of them was deleted and the other is never to be played again. I am, however, still playing the same character in Final Fantasy XI whom I played back when the game launched, and my main in Final Fantasy XIV is the same character I created when the first version of the game went live. My Star Wars: The Old Republic mains haven’t changed since the game launched, nor has my Star Trek Online captain of choice. I tend to know what I want and stick with it, in short.
Of course, that’s not to say that failing to do so is wrong or worse, just different. Maybe you’re still tooling around on your first character from the launch of Ultima Online, or maybe you delete a character every six months, need it or not. So who’s your oldest MMO character who still gets played? Not the first one who ever existed, necessarily, but then one approaching an august age but still growing and developing?
