What’s the greatest epic fantasy series?

I’m a fan of epic fantasy series.  I enjoy seeing familiar characters going through many challenges and adventures over several books.  It requires a lot of time devoted to just one story.  There are many epic fantasies that I’ve only scratched the surface of.  I know that this question has been asked by many and there are websites with personalised lists of the top epic fantasy series, but I’d like to generate a little discussion here.  In your opinion, what is the best epic fantasy series?  What gets your heart racing whenever the tension rises?  What series has made you wait impatiently for the next part, which you eagerly devoured when you finally got your hands on it?  Please leave your comments!
