I worship it
Graphics environment are so smooth and well designed for the time Oblivion released even with a medium specs computer you can enjoy with best graphics if you have a little better pc and have all options maxed then you are in heaven.
The world is enormous you travel and travel and still you are not even close to where you wanted to go, you find yourself in the middle of nowhere surrounding by hungry animals trying to cast your apprentice spells on them so you can escape and then under some huge rocks behind some trees you see a small wooden door which leads to salvation from being lunch for bears :P and you enter this dark cave not aware of what is in there, crouching and trying to cast spells to see in the dark when suddenly you discover a dead body and his nice shiny belongings around :D.
That is just the beginning of this truly masterpiece of a rpg and everyone must play it and feel what really fun means.
