I stuck with it until I finally grew weary of chasing around for kitty litter. At this point I can't say I'm overly fond of RPGs that have too much of a focus on humor.
I keep meaning to replay this one, as I've not tried out the director's version as of yet. And of course I still need to play the third one! What I do recall is, when I was playing Wasteland two, I had a great time with it.
