I think what Akira meant with "slow-paced" is that it takes ages to finish it. Arcade games usually are 5 minutes fix that won't last too long. Zool has some "deepness" not found in most arcade games, like, wandering hopeless trying to find the exit.
Akira: I've seen this kind of equipment here too, problem is that Amiga doesn't have a start button, just a fire button. And for obvious reasons, you can't make the fire button useless
. I've also seen cabinets with PSXs, SNESs and Dreamcasts that when you insert a coin, a timer appears, and when the time runs out, the controls stop working. It usually lasts for 10 minutes.
AEV: I think you are talking about Area 88, which is the other name of U.N. Squadron.
