A really good game has the whole package. Anything less is good, just not really good.
AFM with a WOZ theme would still play good, but I'd still not call it a great game.
On the topic of WOZ, I hope it is out there and accessible on location so I can get to know it. That will give me more reason to want to get in on a future JJP game if finances allow.
For the general public, WOZ is a great theme, just not to sure about in my home.
