Bootlegs and clones and the companies that produced them are fascinating and important parts of arcade history, especially in this part of the world. I get the impression that there was less of this in the US.
Personally, I would rather own a BG Video Falcon than an "original" Centuri Phoenix imported from the US.
Phoenix was a very cloned game, lots of different cabs and romsets, there were 33 in mame the last time I checked. I'm not even sure what constitutes an original and I certainly never saw any Centuri cabs back in the day.
