I purchased AMH #15 used and have had it in my collection for about a year. I bought it without having played it based on the theme, limited nature and the reviews and videos posted by Coast 2 Coast, Buffalo Pinball and others.
Pros - cool and interesting shots (like the jump ramp, hellevator ball lock, opening door and basement subway), varied rules and objectives that allow for different strategies, funny animations and audio clips that are campy, great service and support by Charlie at Spooky. The modes are extremely varied and present more than just "shoot the lit shot" through story animations and audio clips.
Cons - backglass is not great in my opinion, some ball sticks (especially if the game is not set perfectly or is nudged enough), game is darkish out of the box.
The game is not leaving my collection any time soon. I play it all the time and folks who come over to play gravitate to it instead of other games in my room.
