I was checking my total campaign playtime for Halo 3 in the MCC today, and according to the in game stats, I have played the Halo 3 campaign for almost two thousand hours. More specifically, my time is: 1907:71629:4294971. It may shock you to hear this, but I’m fairly certain that that number isn’t accurate.
I checked my other times, and Halo 3 was the only one with this issue. Any idea what might be going on here?
