Stories are inherently molded by their format. A novelization is different from a movie: it typically will include scenes and lots of interior monologues absent in its model. The same happens in any adaption – the original format has certain strength and structures, the new one does things differently.
Starport is a TV pilot: it declares that in every second the reader experiences it. I also found it to be a somewhat quaint TV pilot, in the ’80s/90s vein, because George R.R. Martin wrote it as a script in 1993 and it’s been mostly sitting in a drawer ever since. (It was published, as a script, in the GRRM collection Quartet nearly two decades ago.) But it was available, and, for whatever reason, it was dusted off and artist Raya Golden took that TV script (of what seems to be long enough for a three-hour TV movie, planned to launch a series, and that length may be a clue why it never happened), adapted it into a comics script (of about 260 pages, if I counted correctly). Golden keeps the TV beats and structure: Starport in its graphic novel form is divided into twelve chapters, each one just the right length to fit between commercial breaks.
In this universe, the inevitable Harmony of Worlds contacted Earth the day after tomorrow (Super Bowl Day, to be exact), and invited us to join the previous 314 species in intergalactic peace and prosperity. Starports were built in Singapore, Amsterdam, and (last and most troubled) Chicago.  That last one is the focus of the story, and smart people will realize all of that allows the production to use normal US exteriors and sets, with just a few skiffy specifics and a lot of rubber facial prosthetics and a few carefully-husbanded FX shots to sell the aliens.
It’s a post-ST: TNG SF pilot, with no hint of X-Files, to place it in time — DS9 and B5 were in development when Martin wrote the script, and he may have been able to see finished episodes before he turned the Starport script into Fox. Possibly more importantly, it’s post-Hill Street Blues, and I would not be surprised if one of the pitches was “What if ST: TNG aliens were in HSB Chicago?”
This is a cop show, with a large cast. We have the new detective getting promoted and joining the precinct responsible for the Starport; we have his new partner, the Buntz character; we have two duos of uniformed cops; we have the tough-as-nails female sergeant and her tired-and-ready-for-retirement captain; we have the honor-obsessed alien cop whose anatomy is compatible enough to be fucking a human main character secretly; we have the womanizing, super-successful undercover cop; we have a harried and potentially corrupt alien starport overseer; we have a bar where all the human cops go to drink together and make sure the reader can keep them and the plot straight. I may be presenting them all as stereotypes; in my defense, they are stereotypes. The point of this script was to establish exactly which stereotypes each of them were, to slot them into a dependable American TV framework and allow the actual actors to start expanding those roles if and when it went to series.
It did not go to series; it was never produced at all. And twenty-five-plus years later, it’s so much an artifact of its time that I doubt it ever could be. So this is the only version I expect we will ever get, with Golden’s slightly cartoony art well-suiting the era and aliens but falling a little short on the moments of high drama.
Technically, Starport is a complete story: it sets up a conflict and resolves it. Several major characters have arcs as well. Realistically, it was designed to set up larger conflicts and concerns that Martin hoped would run for several years in a prominent hour-long prime-time spot nationwide, and give him a lucrative showrunning job for the mid-90s. That did not happen; after Starport, Martin felt burned out on Hollywood and focused his attention on what he planned as a fantasy trilogy, starting with the novel A Game of Thrones three years later. (You may have heard of it.)
So this is a road not taken, and, frankly, I think any Martin fan reading it will be happy about that. This could have been a decent TV series, maybe better than that. It could even have broken out and been a massive sensation, as X-Files was about to do at the same network Martin pitched Starport. But Martin’s prose fiction is better than this, and we’ve gotten two-plus decades of that fiction since then in large part because Starport failed.
And now we also got something like the pilot of Starport that never happened
, so I think we’ve gotten the maximum we could reasonably expect.
 That the backstory of Starport includes a Super Bowl in Chicago is the least likely thing about it.
