A lot of people who say they never fast travel are fibbing.
In related news, a lot of people like to make up statistics based on imaginary information.
Just open up the console and type in fasttravelenabled 0. There you go, no more fast travel, and you don't have to use up computer resources with a mod to get it done.
Cool! I wonder if it would enable me to put my freakin blue marker within 20 miles of a city. I'll have to try that. Thanks for the tip!
Lastly, addressed to no one in particular, I just wanted to respond to a lot of people who have said that for them the game is "about" exploring and enjoying the scenery. Interestingly, I thought about that and realized that I don't really care about the scenery, or even exploration really. I am very goal-oriented and almost always "on task" for my current quest. For me, it truly is an issue of immersion. When I spend half an hour trying to find a way to climb up a mountain, and being surprised by trolls and bandit attacks on the way, I feel like I've really accomplished something when I finally get to the top, just by getting there at all. Then when I actually do whatever adventurous thing I came to do, it lends a very epic feeling to the proceedings. When I fast travel, all of my accomplishments become far less weighty; they lose their "oomph".
So I guess, for me, fast travel turns the rest of the game shallow and insubstantial.
