I feel like I'm swimming upstream in polluted water when I read other works out there for purposes of trying to see how something I would want to write might fit in.
It's bad.
A lot of what I skimmed over were Mass Effect clones, but somehow further right wing than Mass Effect already was, with the names changed and the numbers filed off.
A lot of what's left involves "humanity fuck yeah" space imperialism, grizzled tough guys with cold piercing stares and powerlifter physiques well into old age and their adventures with brilliant and hot scientist women that are defined more about who their father is/was and less by their actual job, that try to prove they are Independent Strong Willed Women but of course swoon for the timeless grizzled ego insert's blandly stoic charms. Also, a space bureaucracy usually interferes with the grizzled tough guy's very important imperialistic mission and his only chance to save humanity is to go rogue with a ragtag bunch of renegades and kill those filthy aliens before they threaten colonial interests. Or something.
I got some pretty harsh negative feedback for my inclusion of ideas in my own work. The idea that billionaires wanting to colonize Mars aren't actually going to save humanity by doing that and it would be an insatiable resource sink that would further accelerate Earth's decay was especially incendiary. Maybe I should have already become a rich and influential writer first before trying something like that, but that seems like it might have involved writing one of the above reactionary works instead and hoping another off-brand Mass Effect got more traction instead.
I'm demoralized, but I'm also nearly done with the third book in my self-published trilogy. It's a weird place to be.
EDIT: I may as well post a link to the website my wife and my friend helped set up. It has the first five chapters available for free and some other stuff.

One reason why I think earlier movie adaptions did a better job of it.
House Atreides has a very Liberal Democracy vibe to it, in so far as its got the trappings of modernism and progressivism and rationalism. But they're still doing the same evil shit. Leto Atreides seeks military alliance with the Fremen in the same way that the CIA sought military alliance with the Bin Ladens. The Evil Harkonnens rule with an iron fist while the Benevolent Atreides attempt the same with a silk glove. But they both play the same game, courting the Emperor's favor while obliquely maneuvering to unseat him.
One aspect of the novel that often gets overlooked is the viewpoint of the Planetologist Liet-Kynes, who posits that - absent the constant scouring of the sands for Spice - the planet might become a bountiful ecological paradise. Further, various characters note the rather stagnant state of the Empire, particularly in so far as it remains reliant on Spice long after technological advancement should have rendered it unnecessary.
In Text, the Atreides are the "Good Guys" and the Harkonnens the "Bad Guys" and everyone else is just a bit player. But go to the subtext and you'll get a very different story. This is very much a book about the Cold War and the Gas Crisis of the 70s. That's why it resonated so strongly after it was written. And it requires a second look at the Bene Jessuits and the Spacers Guild and the Emperor himself as prime movers in this Space Opera. The Harkonnens and the Atreides are merely playing their roles within a much grander game. Their relative morality is as much a consequence of deliberately engineered genetic breeding, economic pressure, and political horse-trading as it is of their own personal virtues.
Apply a little materialism to Dune and you'll find it resonates strongly.
