All the times my friend and I have seen have been around 48 hours and thats not 100% and in hero mode. Our best time 100% including hero mode is 40 hours. That is including the hylian sheild, all gratitude crystals, all heart peices, all items upgraded and all goddess cubes and corresponding chests. We invite you to tell us your 100% completion time. Can anyone "HONESTLY" top that? Let us know.
