Quoted from PDXGeek:
AFM is the single best machine to learn how to play pinball on. It has all the required shot angles, and forces you to learn all the flipper control techniques necessary to compete. I literally bought AFM just to practice flipper control.
I am planning on getting a booth at PAX Prime this year, and hope to have several machines up. Hope to see you guys there!
AFM is great in most respects but it can be difficult to demonstrate post passes on it.
T3 is also a great demonstration game. The launch from the middle (skill shot? been awhile) is perfect to demo drop catches.
