Been looking at Faster Than Light: Nomad. It’s got a CC-BY SRD, and looks like a solid system.
Kind of thinking of a space soldier game. Basically life in the trenches of a 40K guardsmen, or starship troopers. Human with a laser rifle and basic body armor entrenched in a hopeless war on an alien planet. WWI in space.
But the trick is not to make it too depressing, while not making it heroic as well.
