Sure, plenty of times, though I just tend to take the same character, and re-envision them, like they're older, or something happened in their history to give a bit of change to their personality, or they get a bit ore maturer being older etc. It works out so that way I can reintroduce them to a new holt or environment or just throw them into an rpg session with a friend.
Works out well enough, although, I haven't much dabbled in the EQ universe for a number of years now. Lack of interest, RL issues, and the loss of old holts just took my enthusiasm for it away.
