If I recall correctly, at one time there was an NPC, that when clicked would tell you the total time you had spent in Paragon City.
If my memory is correct, does anyone know which one it was?
Would that be good information to use to promote an individual's interest in the game? I can easily see people getting a negative impression from a number like that. "You spent 10,000 hours doing what?" might well be the reaction you don't want people to have.
