Which indies did you discover and would love more people to know about? I’ll start: The Pale Beyond. Not sure if it’s a hidden gem tbh, but it’s such a good story rich game. I laughed, I cried and felt the characters struggles. If you like story rich games/ choices matter, check it out.
Starsector: It’s an Elite style open world space game. What makes it special is that it’s been in constant development for over a decade and has a crazy number of ships, weapons, lore and features. And a vibrant modding scene.
Also the devs are vehemently against DRM, so the only place you can buy the game is their own website. Or not buy. They put the full version up for anyone to download.
I’ll have to check that out. An indie game in a very similar vein is Evochron Legends. It’s available on Steam, too. I have a couple of hours in it, but it’s been a while since I last checked it.
