I have a plan set out that goes as follows: Get to Gamestop at 3am on Saturday. Camp... Get game at midnight. Get home at 12:30am on Sunday. Play until ?:??p.m. I think something along the lines of 20 - 30 hours depending on how my friends hold up. I played Zelda when I got my Wii for 26 solid hours minus 3 bathroom breaks and chewing food that was brought to me.
