MMF is the evolution of click and create and Klik and Play, its really easy to use and can make fairly complex 2D games without any real coding, the coding is done inside an event editor when you literally just create the event and tick boxes, coding can be done too but the event editor is a great way of getting inexperienced people started on their first projects. I suggest that if he wants to seriously make a game he considers MMF, its easier to get to grips with than GM6.
