Quick tip - GOG and Amazon Prime Gaming have teamed up to give subscribers an offer they can't refuse - another free game! Get a copy of Stellaris from Paradox Interactive / Paradox Development Studios.
How to get it? Easy. Just head over to Prime Gaming and click the Games header, then you will see that you can redeem Stellaris on GOG. The offer is open until March 1 and the deal is open to any region that is available with GOG, so you should be good to go. Always nice to get another free game and Stellaris is one where you can happily sink 100s of hours into even without any DLC.
For those who don't mind using the Wine compatibility layer directly they also have World War Z: Aftermath from the Epic Store (you can use Heroic for that on Linux!), plus Star Wars Jedi: Fallen Order on Origin (Lutris support incoming).
