Significant for being the first computer-generated graphic novel, but, not surprisingly, it hasn't aged well. Computer graphics of the time (1988) were not capable of creating the level of art that a good comic artist could. Both are a series of still drawings on a page, but a good comics artist is capable of instilling a sense of motion and dynamism that just isn't there with the CG of the day.
Story-wise, it is far more of a cyberpunk story than a superhero story. Set in the distant future (for the time of writing) of the latter years of the second decade of the 21st century, it is a story of corporations at war with each other, of industrial espionage rather than world domination - there are no supervillains, only corporate warriors with biochips implanted in their skulls.
Also, this is not the Iron Man that would be familiar to comics readers of the time - gone are his repulsor beams, replaced by a kinetic energy rail gun, gone too, are most of the tech gadgets that Tony had built into the armour. And way too much technobabble.
Interesting as a piece of comics history, but not much else.
