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.
I backed Tales of the Valiant and Shadowdark and probably a few others I’m forgetting, but I find I can’t get excited about them because at their heart, they are still 5e D&D and I’m just tired of anything directly evolved from D&D. I’ve played enough of them over the years, and I really want new games.
That said I’m excited by the new version of Talislanta, even though I don’t expect it to be very different at all. But that’s getting a classic back in print.
