I don't think Wrath of Khan would have been made, or at least not in that way. And it's quite possible that we wouldn't have had Last Starfighter or Battle Beyond the Stars. Which would have been a shame.
Before Star Wars science fiction was not a big money maker genre for movie companies. Star Wars changed that.It's dificult to over-estimate just how influential and ground breaking Star Wars was. Fathers wpuld take their sons to tje cinema to watch it, then both would come out with their jaws almost scraping the floor. Then join the queue to buy tickets to watch it again.
The music, the scrolling text, that Star Destroyer, Darth Vader, the Death Star; wonder after wonder.
It created a new religion; it even changed some people's lives forever. Almost 50 years on people are still discussing it, going to conventions, cosplaying, buying the toys and reliving their youth.
Because it was special in a way that no movie had been before, or probably will ever be in the future. It opened their hearts, their minds, and made them see science fiction for the spectacle it had always promised to be. And that promised had been fulfilled.

Superman would have still been a hit and it was already filmed before Star Wars came out.
It was too difficult to imitate the design and visuals of Star Wars--so all the copycats--especially Battlestar Galactica which had the most advantage since it hired Ralph McQuarrie and John Dykstra--still put the focus on character interplay rather than action scenes.
It couldn't imitate the action choreography. And it couldn't provide the same kind of fantasy immersion.
Likewise with Raiders of the Lost Ark, all the rip offs could not match the stunts or the ILM fx.
It was simply out of reach because in the days before digital involvement, very few could provide the kind of visuals (and sound design).
I'd like to have seen that version Dune.Maybe no marvel
Perhaps Dune by Jodorowsky becomes the first big sci-fi project, and sci-fi has to wait for its popularity but when it hits it hits on a more intellectual level and it doesn't get comic-book-ised
I remember that. Great exhibition. I intend to visit the museum in Tenby which is where they built the full size Millennium Falcon for the Star Wars movie. There's a permenant exhibition there.I went to a Star Wars exhibition a few years ago in London. The models uses for the movie are astonishingly detailed.
Alien also drew a lot of inspiration from Jodorowsky's Dune which had a very colourful take on how spaceships would appear. Maybe instead of 50 years of dry, grey shapes we could have had some mind-bendingly fun colours as the default.I doubt Alien would have got made. Or if it did would have looked far prettier. There is an interviews with Ridley Scott where he says that on watching Star Wars he knew what spaceships should look like. All used and lived in.
