In any case, what's your favorite starting zone out of all the MMOs you've played? What evokes the strongest sense of nostalgia, provides the smoothest leveling experience, showers you with wondrous atmosphere and tells the best story?
Some MMOs add newer starter zones long into the lifespan of the game, forcing players to choose between the creaky "old" newbie areas and the spiffy golden eggs that the devs just laid. As a bonus question, do you prefer these newer starting areas to the original ones?
