This is FTL but fleshed out and with a load more depth.
There is a Demo available on Steam at the moment: https://store.steampowered.com/app/873940/Crying_Suns/
Played the demo, loved it so far. Very similar mechanics (fuel, scrap), but with extra things in the form of Commandos for planetary missions (RNG) and the combat is a lot more fun, where you can assign officers to weapons/hull/ships, and they have their respective bonuses.
Insta-buy for me
