Since Paizo is going to create a space opera equivalent to Pathfinder, would it be a good idea for Wizards to create a new version of Star Frontiers to compete with Starfinder? They would have both a high fantasy game and a space opera game to compliment each other.
Perhaps as an Unearthed Arcana article. But as a full-fledged setting? Not really. There are plenty of better sci-fi RPG's and settings out there, though. So, personally, I wouldn't be interested. (I'm also not interested in Starfinder for very much the same reason.)
Someone did a 5e conversion of Star Frontiers in the magazine Star Frontiersman.
I would love to see WotC (or somebody) produce a space opera version of 5e. Maybe a Star Wars-type thing with the official serial numbers filed off. I tweeted Rodney Thompson about this when 5e first came out.
