Morrowind - Literally flying

If you have ever used the levitate spell you know that it kind of like flying, but not quite. However if you combine this spell with really high speed, it is exactly like flying. Just use the fortify attribute glitch to get your speed to about a thousand and then go outside somewhere and cast levitate, you can fly very high above the ground and go just about anywhere in the map.

You can also use levitate with the "get of the map" trick that I mentioned in an earlier post to fly around a building and drop down into almost any room.
