>>46772635depends if you want to finish the game story only OR live through it whole, like all the 120 shrines, the memories to be found, the guardians rescued, the 2 DLC´s... its in total a few hundred hours, excluding all the 900 korok seeds to be found, since you effectively need 441 only for all weapon and shield storage upgrades.
it has a lot to do, i played for 300 hours on normal mode, then started a second playthrough on Master Mode (DLC) which is hardcore mode with enemies regenerating health, all enemies are a tier above normal, and you really need to strageize where you can just normally waltz though enemy camps
