My parents and I have noticed that bad guys FOV can see a LOT further now though ironically view distances seems to have been improved a bit where you used to have to go almost up to the monster camp before they 'appeared' suddenly but now you can see them quite a ways. But they can see you now and blow their horns almost right away!

You could in the beginnings sneak up almost right up to them to do sneak strikes but now it's all but impossible without serious stealth foods to the max. Even with your sneaky stuff it isn't any good now :/

Anyways another interesting change is carrots especially endura carrots are not as easy to farm they hardly have any now even at the Fairy Fountains they are very very rare and don't restock very often.

I learned that carrots are actually BAD for horses IRL and can give them indigestion we had horses across from our old house and the owner there told us that and it makes me wonder if people might have complained to Nintendo or someone within their circle told them and they promptly made it harder to farm them?

The Fairy Fountains now only have 2 endura carrots and you can't spam them on Satori Mountain anymore either. I used to get gobs at the Fairy Fountains and just recently there aren't any fairies either. I had some blood moons and they should've respawned especially at the Kakirkio fountain as I forgot it even existed for a long time and went to recently collect some and they are not there! No Fairy fountain has them! I haven't collected fairies for at least 2 blood moons so I would've assumed they'd respawned by now?
