Good thread here and interesting discussion and input by many.
I have a friend that has a Houdini and I had a chance to experience the machine for a couple hours one day. I am not that great of a player and while I found some shots hard they were still doable. But I agree with some posters here the game would have probably been a bit better if maybe one less shot was built in the game and the remaining shots were a tad wider. Overall I like the way the game presents itself and plays.
I have thought about getting a copy of the game myself.
The only thing that I would maybe take issue with is the way AP has handled the power issue for game owners. Sending the owner the part needed vs a credit or voucher and charging them for the part to fix the machine would buy a lot of goodwill. Those owners might be more inclined to buy another title in the future from AP if they just provided the service part free of charge or even at a very nominal fee to cover the shipping as the part needed isn't a cheap item and might not be needed on all copies of the game - or may be related some to home outlet voltages ? I'd still think providing the part free of charge is the right thing to do and worth the goodwill it would yield.
Maybe I will see this game in my collection one day.
