That was my experience as well. Although exploring the world was initially interesting -- and I enjoyed outfitting my character with a fez -- after a while wandering around squeezing chickens got a little dreary. And when you leveled up and learned new skills, most of the time they weren't all that interesting. Becoming 10% more efficient at gardening or whatnot.... It definitely seemed to be lacking a hook of some sort. I bet there are some interesting lessons for game designers there.
