Being an owner of all 4 zizzles that were commercially released I will say that I was very disappointed when this title (and zizzle) was scrapped. It would have been nice however to see some alteration to the playfield (aside from art) to give it some uniqueness compared to marvel heroes and potc.
This price point on these machines was a bit high when they were for sale ($400 range). I'd say that if the machine was just a little more sturdy they would have been worth the money. The stock flipper buttons were AWFUL. The plunger was prone to breaking if forced too hard. Coils would burn out if buttons were held on for too long. Occasionally a ball would jam in the pop bumpers and cause them to break or burn up. The 1st gen machines had 2 design flaws where a wild ball could get stuck behind the rails that define the playfield or get stuck behind the plastic targets, with the only remedy being to flip the whole machine upside down to unstick the ball. Gen 2 fixed this problem by covering the unused playfield area with plastic so the ball couldn't get stuck and a redesign of the plastic targets which prevented the ball getting stuck.
I saw several (and bought two) dead zizzles that had fried PCB/MPU boards. I have a theory that if a kiddie held both flipper buttons down constantly for too long it would blow a voltage regulator on the board and fry it. These had no type of end-of-stroke switch to drop the 24v running to the flipper coils.
Had all of these things been corrected (especially the buttons) and maybe a few GI lights placed in the machine then in my opinion $400 would have been well worth it.
On a side note I modified a few of my machines with an Arduino board and added real arcade buttons and scrapped the stock buttons. This made a HUGE difference. The Arduino handles all of the coils with a separate power supply to protect the MPU/CPU. I coded in virtual end-of-stroke so after a half second the controller drops the voltage by 80% to the coils to prevent burnout. Also coded the pop/slings to 'pulse' power to them instead of staying on constantly when the switch (skirt) is activated. Also added a 3-second safety shutoff so if any coil is on for more than three seconds the code shuts off power to that coil. Added a bumper post between the flippers since the gap is way too wide. With these mod the games are actually really fun to play. Too bad these feature couldn't have been provided out of the box. If they were then Zizzle might still be around.
