To me, the game simply has infinite replay value, even though it's not even finished yet. The worlds are so huge that there is an insane amount of exploration possible, building stuff is always fun, and there are so many other things to do as well.

At the rate I'm going, Ashlands will probably be released before I am through Mistlands. I have never really been there yet -- and I haven't even defeated Yagluth a single time. So, there is still plenty for me to discover and experience for the first time.
