Directions mean that you have to follow them, you can't stray from the path otherwise you get lost.
Would you like me to hold your hand so you don't get lost?
That's a consequence of the system that I like, it's not a negative.
In the same way that if you fail to fight properly you die, you fail to navigate properly you get lost. There are consequences.
Exploration is when you're not told where the thing is at all, you have to find it yourself.
Not true. Exploration is the act of travelling through an unfamiliar area to learn something/find something.
One could be given directions and still explore, since the area is still unfamiliar and they're still trying to find something.
Nevertheless, in my eyes this point is moot anyway. Even if directions was not "true" exploration, it is a much more engaging and realistic way of navigating a World that is built around a medieval framework.
Edit: inb4 "maps are realistic too", maps can be realistic. Maps can also be massively unrealistic.
Let's suggest there's 50 quests where someone requests you go and get something/go and kill someone in a dungeon.
Every single one of those people knows exactly where to within an inch that object/person is and can mark it on your map, even if you haven't been there and your map is blank there? Yep, makes sense.
My last word on the subject.
