What's the most you've ever played a game (and, obviously, which game) in a day/week/consecutive period of time?
My personal "bests":
–Played Star Ocean 3 for 56 hours in one week between Christmas and New Year's Once. (My friend later one-upped me by beating the game in 80+ hours in just six days.)
–Played FFXIII for 31 straight hours shortly after it came out. (During this stretch, I finally got to Gran Pulse, which opened up a massive chunk of interesting gameplay and helped me keep going.)
