I had AFM and MM and enjoyed both thoroughly. They are essentially the same game with mostly the same shots. AFM might be considered a bit faster in my opinion because of the extra loop. It comes down to theme. Personally, I prefer the theme and humor in MM and kept that while selling the AFM. I don't think you could go wrong with either. Call me old fashioned, but I'd rather have an original than a repro of just about anything.
