Goodness gracious, did I love Joe and Mac. I only ever rented it, but I did so some 5 or 6 times "back in the day." It was a lot of fun, and having a second player made it much, much more enjoyable. I'm a little suprised co-op games don't see more production, since there was interest even in the early 1990's for such features, and even now they're still scarce.
