Is there any content unavailable after beating the final boss in Breath of the Wild?
Please keep the answer spoiler free if possible, I am curious how big the list of things to do before beating the final boss is if anything gets locked out after the final boss, or if the game reverts to a pre post game stage after beating the game.
No. After defeating calamity ganon, your save gets marked with a star, but will otherwise be reverted to where it was before you defeated calamity ganon.
