man, you should go and play fallout 1 and 2. The true legends of crpg. Traveling there is never boring. Also check Arcanum. For me Arcanum has the ideal traveling system, the best ever made.
I have played Fallout 1 and 2 numerous times, but the traveling isn't exactly the same as it is in Elder Scrolls games, also taking into the consideration that even though they are old games and software was not so advanced, it was far easier and quicker to program things back then.
Plus it isn't really a 'unique' event when you are attacked by a different 'kind or number' of something, all encounters are scripted to an extent. Developers can only script so much so you will find yourself doing missions that are ever so similiar, they might aswell be the same mission, that doesn't bother me personally because I can feel free to fast travel if I get bored.
But really I would rather them just work on the main aspects of the game over some kind of 'event generator', which only creates alot more missions that have just slight differences so people can call them "unique", when they won't be in terms in gameplay, only in the logical sense. Just wouldn't make the game anymore fun at all, when you consider the game already has the same sense of 'unique' encounters, just in a far simpler and straightforward manner.
That's of course all of my own opinion and I am a biased fanboy
, also a fan of Fallout 1 + 2, not 3 or New Vegas though, they were boring.
