Oblivion in no RPG...it's more an action adventure and this is the point why Oblivion s*cks to me....Exploring cities and wilderness is one off the most important parts of any RPG...if you want someone who takes your hand and guide you in front of the cave (questmarker) you better stop playing Morrowind immediately and return to Imperial City.
No one asked what you think about Oblivion and, quite frankly, I think no one cares, so rather than telling others what to do, YOU should stop posting things that don't contribute to anything and play Morrowind, at least that way you entertain yourself, it accomplishes more than annoying people with pointless posts.
Now back to what actually relates to the topic, the main thing I liked about Morrowind's map over Oblivion's is that it actually shows you where you've explored by having the unexplored map just show the terrain as a single color with the shade indicating the terrain elevation, whereas once you explore a square, it takes on the actual colors of the terrain there. Sure, in Oblivion, I could technically tell where I've explored before by looking at the amount of locations I've discovered in an area, but to the explorer in me, it just didn't feel quite as satisfying as actually seeing he map starting to fill in with color, square by square. The problem here is that once an area was explored, I had a hard time making out the actual structure of the terrain there, I could just see the sort of color's it has, so what I really wish could be made is a map that would reflect which parts have been explored while still allowing the terrain structure of explored areas to be easily visible. Unfortunately, I don't know how one would approach that.
