Quoted from Rarehero:

I finally played the Pro last weekend. First impression: Just terrible. I'm not going to claim I understand the nuance of the game, if there is any....but every ramp shot feeds to the ring, and the ring is the most boring main feature I've ever seen in a game. After blerping the ball back and forth for 10 seconds up there with those weak-ass ropes, I was ready to give up. It's coded "video game style"...like X-Men, which frankly - sucks. Pinball can't be programmed like Street Fighter or Punch-Out. The whole player vs. the guy bobbing up and down on the DMD just doesn't work. I'll be happy to never play this game again.
