Hey there!
I'm ImbaMarines and outside of my prime work as a software dev, I make (and run) TTRPGs.
Are you looking for something that's high on improv, focuses on the narrative and is in realm of soft science fiction? Well, look no further than Ash Collectors.
Crave for combat and pushing miniatures across the table? I got what you need, especially if you think that choice of weapons should matter beyond just damage: The Scorched Banner.
