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.
Dominions (Dominions 6 just came out, but it’s an iterative game so try 4 or 5 first)
So it’s like civilization and battle simulator had a baby, where armies are managed by the unit and there are simulated battles of thousands.
But all the civs are loosely based on different existing mythologies and there’s a crazy complex magic system
Oh, and you get to create a god that you can totally battle with.
If you like civ-like games, it’s a really unique and satisfying twist on the genre with an incredible amount of sheer depth.
