I did for a long time, now I'm addicted to Morrowind. I only get to play a few nights a week, but when I do, I'll say to myself, "OK, I'm just gonna play for an hour". Then before I know it 3 or 4 hours have gone by.
I played it for months until my computer crashed and lost the saved game files. I did not feel like starting over so I just stopped playing. I was really close too, almost ready to take Diablo on himself.
