I've been playing Oblivion a bit lately, and I took note of, IMO, the single most differentiating factor between games, other than the obvious changes. The element I speak of is fear. In oblivion, I at least, feel fear when entering a cave, fortress, ruin, oblivion gate, and even just walking around. Skyrim on the other hand gives you the feeling of saftey and security throughout most of the game.
My question to you is, if you do, how do you implament fear and excitment into your playthrough?
Thanks in advance.
