If I could pick two games they'd be RPGs (+boardgames +miniatures!) based on The Expanse or Ash vs Evil Dead! Both shows are in their second seasons this year, and Expanse book 6, Babylon's Ashes, is out in November.
What if the way leads to the world where humans share characteristics of insects, the realm that is known as the Shadows of the Apt.
Or the First of the Antiheroes, to visit the lands of that albino King with the Soul devouring sword.
And another hint, there is Human Interface Nakamura Tower from Postindustrial Games who are thinking about making a rpg of their setting. I mentioned Modiphius on their kickstarter as possible partners for a rpg.
What I would very much like is you to finish the work started 3 week ago when we got the Infinity RPG Gear Chapters which for reason was missing the Prices rendering them useless.
I would really like to play the Infinity RPG a RPG we was promised would be ready in January but now 6 months later we still do no have enough of to actually play.
The Dune saga. And, if that's even possible, being inspired by or even incorporating Alejandro Jodorowsky's vision of Dune. Perhaps as a sourcebook that contains an alternate take on the Dune saga. That would be awesome, or his Ingal, which contain these fabulous idea's that I saw in the documentary.
Another possibility is to make stand alone rpg's. Like:
He-Man: By the power of Grayskull
