Oblivion has been teaching me lately that if you run around enough you will eventually be able to fly and run faster than horses!.
And also that horses and people magically know when they have not been acquired legitimately.
Things I also learned from that game:
-The vampires are the black people from the past: No matter if they had to save the world, people just won't talk to them.
-All medieval guards have X-ray goggles with SoB (Stolen or bought) detector on them.
-Don't be afraid of destroying alternative universes, you will get teleported to your original location after that.
-The stores have everything the world needs to be saved, but no one wants to get out and do something.
