There's so much stuff like that in the game! My brother comes by regularly to play on a separate account and while we try to go to different areas there's still quite a bit of overlap. It's incredibly how much stuff is in all those areas that he visits that I haven't even seen, but it's even more incredible how much stuff one of us missed in the areas we both explored.

And considering that we're both pretty serious gamers and compulsive 'find everything' personalities, I suspect more casual games could replay the game from the start multiple times and still discover new stuff that is 'significant' (as opposed to 'minor' stuff like new items, korok seeds, or shrines).

It allows you to store extra swords, shields, and bows AFAIK. Also has a couple of tools (hammer, others) conveniently available nearby.

I liked the weapon storage for keeping certain useful/powerful weapons, especially since it took me forever to find Hestu's second location, and the bed is nice to have as well. Mainly just a fun thing to have, and I'm hoping they pop something house-related into the DLC.
