Me? Well the first time i had some help from a friend, and the second time i just knew where everything was. Well i think it was 30-40 hours the first time, but it may have been 40-50. I'm not too sure, it was a while ago. Plus the game got deleted, so i cant confirm it.
I heard that the record was like 5-10 hours or somthing. I dont belive it though, with the talking and stuff.
