Its a bit better with "Win Capture." I am also trying to narrate as I go instead of trying to narrate afterwards
I tried using my speakers to get game audio into the recording, but I think I'll ditch the music, much as I love it, as there are too many distortions. I think I'll let the sound effects permeate, though, as they help provide a sense of feedback from what's going on, on-screen, especially when I skip or end turns.
