I played the game a year or two ago and i must say i thoroughly enjoyed it
It wasn't quite the gaming experience of a lifetime, but it was worth the money. I respectfully disagree with you on the Peter Molyneux front, to me he's still making good games, but he's taken the foot of the gas a little, and there are so many other developers out there now that he's not the visionary games creator he once was.
I haven't played Harvest Moon, so I don't get your comparison there - but I hope the game gets more entertaining for you later on. I still haven't played the expansion pack...
