Watched 4 episodes last night - agree on the english subtitles, the dubbing put me off within 10 mins of the start, so started again with the original korean voices. I think the pay off is greater, dubbing doesn't get over the emotion of the characters, but my god the woman who is in the bad guys gang, her voice is like nails over a chalkboard.
As for which games i would fail on......so far only seen 3 of them and i'm pretty sure i would be done in all 3.
