Clickboom released a game called T(rauma)-Zero, but Ive never heard of "The Zero" :)
On a more serious note it's a shame these things go for such crazy prices these days. Understandable (to an extent), but a shame nonetheless. Weirdly enough, I suspect high quality products today would sell just as well as they did at the tail-end of when Amiga was relevant to more than nostalgic enthusiasts. Seems a good portion of us remaining are more willing/able to purchase luxury items than "back in the day" where piracy was rampant (so silly in hindsight,.... piracy was clearly delegating the Amiga to shoddy versions of multiplatform software and lots of sub-pd quality stuff by this point, but people would still pirate the few good quality titles en masse without a 2nd thought).
