I couldn't imagine playing one game and especially not one character for over 25 years like that... That's just strange to me.
My longest RPG character was a Star Wars D6 character that got used weekly for over four years. My longest D&D characters were a 3.5 character that went about two years and my current 4th character that's going on 2.5 years now, I think. Too much changes to stay with anything long for me; DMs get bored (the biggest culpirt of campaigns ending early, in my experience), people's interests shift, people want to try out new characters or games.
