Exactly my point. There is less information infront of you on a 2D map.....you just get the general layout of things....so when you go to that huge gorge you only have a basic idea of its shape and location....as opposed to seeing it in advance in a tiny 3d scale model view, which just ruins the experience of finding out what its like for yourself, as youve already seen it.. I personally(that means my opinion) prefer to have a more vague 2d map where i actually have to find my way around, compared to a an exact scale model that ruins the grandness of the game by showing it in the tiny view before you experience it for yourself.
So you want less content, not more, implying that you're less concerned about content and more about aesthetics and immersion.
A simple topographical representation of the area, while pretty, does not tell you exactly where everything is, either. Seeing it for yourself will definitely be a different experience from seeing it on the map. Always.
