Twice, both Tomb Raider. Once the game didn't record so I had to make a second file and play the whole game up until that point, then another time, my commentary didn't record, so I had to record the commentary by watching it and pretending to be playing. When I ran it past my friend she said she couldn't had known different if I hadn't told her, so it clearly worked. Dangsammit it Lara, why you being so difficult?! xD
