It was obviously rushed. A friend of mine beat it in 7 hours. He didn't hunt down the dead drops because they seemed irrelevant to the story to him (unlike in inFamous 2 which he loves).
What? Are the dead drops the audio files? They were very interesting and give background information on Eugene, Fetch, and even Augustine. They're even more intresting if you play the Papaer Trail mission. Can't wait for part two. I love a good mystery :D
