What is the most amount of hour's you put into a video game?

my dark cloud 2 save is 70 ish hours, my warhawk play time was 65 hours last time i checked (that's only on ranked servers). other ones I assume would be pretty high, though I don't have numbers (I don't play these anymore)

ultima online (easily in the 100s of hours)
