I think it's great!
Especially for the wife factor. Since she doesn't LIKE to sit an play lengthy intense games that require tons of time and a high level of coordination to master. Or, just for those nights you're just too lazy to bust out a can of whoop ass and still need something to pass the time. It WOULD be nice if they were a bit cheaper, or if MS decided to offer a freebie every now and then (since I'm a cheap ass, and all.)
