Doing some surfing on pinball software design and stumbled across this business that personalizes pinballs.

thats a neat set up.   you can custom it up yourself which is nice idea.  basic layout is the same for the machines.  but you get to fill in the blanks and the sound.
   wonder the price.   but for a company (like most of them are) its a neat tradeshow idea.

Firepower I suppose is the obvious playfield layout, lots of space to show logos, no ramps, very simple. I wonder what kind of electronics/software they use.
